Logbook vs Kilometre Rate Calculator NZ 2026

What are the two ways to claim vehicle expenses in New Zealand?

The actual cost method claims a share of what the vehicle genuinely costs you, including fuel, servicing, tyres, registration, insurance, repairs and depreciation, apportioned by the business use percentage from a logbook. The kilometre rate method claims a set amount per business kilometre using rates Inland Revenue publishes each year, with a higher tier one rate for an initial band of kilometres and a lower tier two rate beyond it. You choose one method per vehicle, and the choice generally applies for as long as you own it.

Which method gives the bigger claim?

It depends on how expensive the vehicle is to run and how far you drive for business. The actual cost method tends to win for expensive vehicles with high fixed costs and a high business use percentage, because depreciation and insurance are claimed in proportion regardless of distance. The kilometre rate tends to win for cheap, efficient vehicles driven a long way, because the rate is paid per kilometre whatever the vehicle actually costs. Running both, which is what this calculator does, is the only reliable way to know.

Do I still need a logbook if I use the kilometre rate?

Yes. You need evidence of the business kilometres you are claiming whichever method you use. A logbook covering a representative period of at least 90 consecutive days establishes a business use percentage that can then be applied for up to three years, provided your usage pattern does not change materially. Without records, neither method is defensible if your return is reviewed.

Why are there two tiers in the kilometre rate?

The tier one rate covers both the fixed costs of owning a vehicle and the running costs, so it applies only to an initial band of kilometres each year. Beyond that band the fixed costs are treated as already recovered, and the lower tier two rate covers running costs alone. This is why the average rate per kilometre falls as business distance rises, and why very high mileage makes the actual cost method more competitive than the headline tier one rate suggests.

Can I switch methods later?

The choice is generally made when you start claiming for a vehicle and applies while you hold it, so it is worth getting right at the outset rather than assuming it can be revisited. If your circumstances change substantially, or you replace the vehicle, the position should be reconsidered. Confirm the rules that apply to your situation with Inland Revenue or your accountant before switching.

Base Converter (Binary, Octal, Decimal, Hexadecimal)

What is a number base?

A number base, also called a radix, is the number of distinct digits a system uses to represent values. Decimal is base 10 and uses the digits 0 to 9. Binary is base 2 and uses only 0 and 1. Octal is base 8 and hexadecimal is base 16, which adds the letters A to F to represent the values 10 to 15.

How do I convert binary to decimal?

Each binary digit represents a power of two, doubling from right to left: 1, 2, 4, 8, 16 and so on. Add up the place values where the digit is 1. For example 1111 1111 in binary is 128 + 64 + 32 + 16 + 8 + 4 + 2 + 1, which is 255 in decimal.

Why does hexadecimal use letters?

Hexadecimal is base 16, so it needs sixteen distinct digits. The digits 0 to 9 cover the first ten values, and the letters A, B, C, D, E and F represent the values 10, 11, 12, 13, 14 and 15. This lets a single character stand for four binary digits, which is why hexadecimal is common in computing.

What is the largest number this converter handles?

Results are reliable for whole numbers up to two to the power of 53, which is the largest integer that can be represented exactly. Above that, rounding can make a conversion inaccurate.

CSS Unit Converter (px, em, rem, pt, %)

How do I convert px to rem?

Divide the pixel value by the base font size. With the common default base of 16 pixels, 16px is 1rem, 24px is 1.5rem, and 8px is 0.5rem. Change the base font size in the converter to match your own root font size.

What is the difference between em and rem?

Both are relative to a font size. A rem is always relative to the root font size, while an em is relative to the font size of the current element. This converter treats both as relative to the base font size you enter, so they give the same pixel value here.

How many pixels is 1pt?

In CSS, 1 point is 1.3333 pixels, because a point is one seventy-second of an inch and CSS assumes 96 pixels per inch. So 12pt is 16px and 9pt is 12px at 96 dpi.

What does percent mean for a CSS length here?

Percent in CSS is always relative to something, and that reference depends on the property. In this converter, percent is treated as a share of the base font size, so 100% equals the base, 50% is half the base, and 200% is double the base.

Flow Rate Converter

How do I convert litres per second to litres per minute?

Multiply the value in litres per second by 60, because there are 60 seconds in a minute. So 1 litre per second is 60 litres per minute.

What is the difference between US and UK gallons per minute?

A US gallon is smaller than a UK (imperial) gallon, so the two flow rates differ. One US gallon is about 3.785 litres while one UK gallon is about 4.546 litres, which means a given flow in UK GPM moves more liquid than the same number in US GPM.

What does CFM mean?

CFM stands for cubic feet per minute, a volumetric flow rate common in air handling and ventilation. One cubic foot per minute is about 0.000471947 cubic metres per second, or roughly 28.3 litres per minute.

Is this a mass flow or volume flow converter?

This tool converts volumetric flow rate, which is volume of fluid passing a point per unit of time. It does not convert mass flow rate, which would also need the density of the fluid.

Length Converter

How do I convert between length units?

Multiply your value by the from unit's factor to base metres, then divide by the to unit's factor. For example, to turn metres into feet, divide the value in metres by 0.3048, because one foot is 0.3048 metres.

How many feet are in a metre?

One metre is about 3.28084 feet. This comes from dividing 1 by 0.3048, since a foot is defined as exactly 0.3048 metres.

What is a nautical mile?

A nautical mile is exactly 1,852 metres and is used in marine and air navigation. It is longer than a statute mile, which is 1,609.344 metres.

How many centimetres are in an inch?

One inch is exactly 2.54 centimetres, because an inch is defined as 0.0254 metres. Multiply inches by 2.54 to get centimetres.

Weight & Mass Converter

How do I convert between weight units?

Multiply your value by the from unit's factor to base kilograms, then divide by the to unit's factor. For example, to turn kilograms into pounds, divide the value in kilograms by 0.45359237, because one pound is 0.45359237 kilograms.

How many pounds are in a kilogram?

One kilogram is about 2.20462 pounds. This comes from dividing 1 by 0.45359237, since a pound is defined as exactly 0.45359237 kilograms.

How many grams are in an ounce?

One ounce is about 28.3495 grams. An ounce is defined as 0.028349523125 kilograms, which is 28.349523125 grams.

What is the difference between weight and mass?

Mass is the amount of matter in an object and does not change with location. Weight is the force gravity exerts on that mass. In everyday use the terms are used interchangeably, and these units all measure mass.

Acreage Calculator

How many square metres are in an acre?

One acre is 4,046.86 square metres. It is also about 0.405 hectares, so roughly two and a half acres make a hectare. An acre was traditionally the area a yoke of oxen could plough in a day.

How do you calculate acreage?

For a rectangular block, multiply the length by the width to get the area in square metres, then divide by 4,046.86 for acres or by 10,000 for hectares. A 100 by 100 metre block is 10,000 square metres, which is about 2.47 acres or 1 hectare.

What is the difference between an acre and a hectare?

A hectare is a metric unit of 10,000 square metres, a square 100 metres on each side. An acre is an imperial unit of 4,046.86 square metres. One hectare is about 2.47 acres. New Zealand land is usually quoted in hectares and square metres.

Acres per Hour Calculator

How do you calculate acres per hour?

Multiply your working width in metres by your ground speed in kilometres per hour, divide by 10 to get hectares per hour at 100 percent efficiency, then multiply by your field efficiency. Multiply hectares per hour by 2.471 to convert to acres per hour. A 3 metre implement at 8 km/h and 80 percent efficiency covers 1.92 hectares, or about 4.74 acres, each hour.

What is field efficiency?

Field efficiency is the share of working time actually spent covering new ground. Turning at the headlands, overlapping passes, refilling sprayers or seed boxes and clearing blockages all eat into it. Typical values are 70 to 90 percent, with mowing and cultivating near the top of that range and spraying or drilling with frequent refills near the bottom.

How many acres can a tractor cover in an hour?

It depends almost entirely on implement width and speed. A 3 metre mower at 8 km/h and 80 percent efficiency covers about 4.7 acres an hour, while a 12 metre sprayer at 16 km/h and 70 percent efficiency covers about 33 acres an hour. Use your own width, speed and efficiency for a realistic figure.

Acres to Hectares Converter

How many hectares are in an acre?

One acre equals exactly 0.40468564224 hectares. In practical use, this is rounded to 0.4047 hectares. Conversely, one hectare equals approximately 2.471 acres. The conversion is exact because the International acre is defined as exactly 4,046.8564224 square metres, and a hectare is exactly 10,000 square metres.

What is the difference between an acre and a hectare?

An acre is an imperial unit of area equal to 4,047 square metres (approximately 0.405 hectares). It originated in medieval England as the amount of land an ox could plough in one day. A hectare is the metric unit equal to exactly 10,000 square metres (100 metres x 100 metres), used internationally and in New Zealand for land measurement. A hectare is about 2.47 times larger than an acre.

Are land titles in New Zealand measured in acres or hectares?

New Zealand officially uses hectares for land measurement, having converted from acres as part of metrication in the 1970s. Most modern land titles, council maps, and rural property listings now show areas in hectares. However, older documents and some rural discussions still reference acres, so the ability to convert between the two units remains useful. A typical lifestyle block in New Zealand is often described as 2 hectares (about 5 acres).

Acres to Square Feet Converter

How many square feet are in an acre?

There are exactly 43,560 square feet in one acre. This is a defined, exact value. The acre was historically the amount of land a yoke of oxen could plough in a single day, standardised in the 19th century as 4,840 square yards, which equals 43,560 square feet (since 1 yard = 3 feet, so 4,840 x 9 = 43,560).

How do I convert square feet to acres?

To convert square feet to acres, divide by 43,560. For example, a 10,000 sq ft section is 10,000 / 43,560 = 0.2296 acres. You can use the reverse conversion field in this calculator to enter square feet and get the answer in acres immediately.

How big is 1 acre in practical terms?

One acre (43,560 sq ft) is roughly the size of an American football field without the end zones (about 48,000 sq ft). It is also about 55 to 60% of a standard rugby league field. In square terms, an acre is approximately 209 feet x 209 feet. For NZ context, a typical urban house section is around 500 to 700 square metres (roughly 5,400 to 7,500 sq ft), which is about 0.12 to 0.17 acres.

Activation to Paid Conversion Calculator

What counts as an activated user?

An activated user has experienced your product's core value, such as completing setup or finishing a key workflow. The exact milestone depends on your product, so define it clearly and keep it consistent. Activation should reliably predict that a user understands why your product is useful.

How is this different from trial conversion?

Trial conversion measures all trial users who pay, while this metric only looks at users who activated first. By focusing on activated users, it isolates how well early value turns into revenue. It removes users who never engaged from the denominator.

What if my rate is low?

A low activation to paid rate often signals pricing friction, a weak upgrade prompt, or unclear value beyond the free tier. Review your paywall, messaging and packaging. Allow enough time for users to convert before judging a cohort.

Angle Conversion Calculator

How do you convert degrees to radians?

To convert degrees to radians, multiply the degree value by pi divided by 180. The formula is: radians = degrees x (pi / 180). For example, 90 degrees equals 90 x (pi / 180) = pi / 2 radians, which is approximately 1.5708 radians. A full circle is 360 degrees or 2 x pi radians (approximately 6.2832 radians).

What is a gradian (grad)?

A gradian (also called grad or gon) is an angle unit where a full circle equals 400 gradians. This makes right angles exactly 100 gradians, which was designed to simplify decimal calculation. Gradians are mainly used in surveying and some European engineering fields. To convert degrees to gradians, multiply by 400/360 (or 10/9). For example, 90 degrees equals 100 gradians.

What is the difference between arc minutes and arc seconds?

Arc minutes and arc seconds are subdivisions of a degree used for precise angle measurement. One degree equals 60 arc minutes (written as 60'). One arc minute equals 60 arc seconds (written as 60''). So one degree equals 3,600 arc seconds. These units are commonly used in navigation, astronomy, and geographic coordinate systems (latitude and longitude). For example, the angle 1 degree 30 arc minutes equals 1.5 degrees.

Angle Converter

How do you convert degrees to radians?

Multiply degrees by pi divided by 180. For example, 90 degrees times pi divided by 180 equals pi divided by 2, which is approximately 1.5708 radians. To convert radians to degrees, multiply by 180 divided by pi.

What is a gradian (grad)?

A gradian, also called a grad or gon, divides the full circle into 400 equal parts instead of 360 degrees. One grad equals 0.9 degrees and pi divided by 200 radians. Right angles are exactly 100 grads. Gradians are used in surveying and some European engineering traditions.

What are arcminutes and arcseconds used for?

Arcminutes and arcseconds are subdivisions of a degree used in navigation, astronomy, and geodesy where high angular precision is needed. One degree equals 60 arcminutes, and one arcminute equals 60 arcseconds. So one degree equals 3600 arcseconds. Telescope pointing, satellite orbital data, and GPS coordinates all use these fine units.

Ares to Hectares Converter

How many hectares is 1 are?

One are (a) equals exactly 0.01 hectares (ha). Because there are 100 ares in a hectare, dividing any value in ares by 100 gives the equivalent in hectares. For example, 250 ares equals 2.5 hectares.

What is an are and where is it used?

An are (symbol: a) is a metric unit of area equal to 100 square metres or 0.01 hectares. It is part of the International System of Units (SI) but has been largely superseded in everyday use by the hectare. The are and its derivative the hectare are still used in land measurement in some European countries and in agricultural contexts. In New Zealand and Australia, land area is commonly measured in hectares or square metres rather than ares.

How do I convert hectares back to ares?

To convert hectares to ares, multiply the number of hectares by 100. For example, 3.5 hectares equals 3.5 x 100 = 350 ares. This is the exact reverse of the ares to hectares conversion, which divides by 100.

ASCII Code Converter NZ

What is an ASCII code?

It is the number that represents a character in the ASCII character set, such as 65 for capital A and 97 for lowercase a. Computers store text as these numbers. For characters beyond basic English, the wider Unicode set assigns code points in the same way.

How do I convert text to ASCII codes?

Paste your text and the converter lists each character with its code in decimal, hexadecimal and binary. Decimal is the familiar code number, hexadecimal is base sixteen as used in programming, and binary shows the underlying bits.

Can I convert codes back to text?

Yes. Switch to the codes-to-text mode and enter the decimal code points separated by spaces or commas. The converter turns each number back into its character and rebuilds the original text. It works for any Unicode code point, not just basic ASCII.

ATM Conversion Calculator

How many pascals are in 1 atm?

One standard atmosphere (1 atm) is exactly 101,325 pascals (Pa), or 101.325 kilopascals (kPa). This is the internationally defined standard, established by the International Union of Pure and Applied Chemistry (IUPAC) and used as the reference pressure in chemistry, physics, and engineering.

What is the difference between atm and bar?

One atmosphere (atm) equals 1.01325 bar. The bar is a metric unit of pressure equal to exactly 100,000 Pa, while 1 atm equals 101,325 Pa. They are very close in value but not equal. The bar is commonly used in meteorology, scuba diving, and industrial settings, while the atm is more common in chemistry and describing standard conditions.

How do I convert atm to psi?

To convert atmospheres to pounds per square inch (psi), multiply the atm value by 14.6959. For example, 2 atm equals 2 x 14.6959 = 29.3918 psi. To convert psi back to atm, divide by 14.6959. Standard atmospheric pressure (1 atm) is approximately 14.696 psi. A tyre reading 30 to 35 psi on the gauge is about 2.0 to 2.4 atm of gauge pressure, which is roughly 3.0 to 3.4 atm absolute once you add the 1 atm of surrounding air.

ATM to Pascals Conversion Calculator

How many pascals are in one atmosphere?

One standard atmosphere (1 atm) is exactly 101,325 pascals (Pa). This is an exact definition by the International System of Units (SI) and is not a rounded approximation. It is equivalent to 101.325 kilopascals (kPa), 0.101325 megapascals (MPa), or 1.01325 bar.

What is the difference between atm, Pa, and kPa?

The pascal (Pa) is the SI unit of pressure, defined as one newton per square metre. It is a very small unit, so kilopascals (kPa = 1,000 Pa) and megapascals (MPa = 1,000,000 Pa) are commonly used in engineering. The standard atmosphere (atm) is a historical unit defined as the mean atmospheric pressure at sea level: 101,325 Pa. In everyday settings, weather forecasters often use hectopascals (hPa), where 1 hPa = 100 Pa, so standard atmospheric pressure is 1,013.25 hPa.

When would I need to convert atm to pascals?

You typically need to convert atm to Pa when working with scientific calculations or equations where SI units are required, such as the ideal gas law (PV = nRT), where pressure must be in pascals if you are using SI values for other constants. Atmospheric pressure data may be given in atm in chemistry and physics textbooks, while engineering software and fluid dynamics calculations usually expect pascals or kilopascals. Weather data is commonly given in hectopascals (hPa) or millibars (mbar), which are equivalent.

Bar to ATM Conversion Calculator

How many atm is 1 bar?

1 bar is equal to 0.986923 standard atmospheres (atm). This comes from the definition of one standard atmosphere as exactly 101,325 pascals and one bar as exactly 100,000 pascals. Dividing 100,000 by 101,325 gives 0.986923 atm per bar. Bar and atm are close in value but not the same: bar is a metric unit while atm is based on the average atmospheric pressure at sea level.

What is the difference between bar and atm?

Both bar and atm are units of pressure, but they are defined differently. One standard atmosphere (1 atm) is defined as exactly 101,325 pascals, which is the approximate average air pressure at sea level. One bar is defined as exactly 100,000 pascals, a round number close to but slightly less than 1 atm. In practical terms they are nearly equal (within about 1.3%), but scientifically they are distinct. Bar is preferred in meteorology, oceanography, and engineering, while atm is common in chemistry and physics, particularly when describing gas behaviour.

How do I convert atm back to bar?

To convert from atm to bar, multiply the atm value by 1.01325. This is because 1 atm equals 101,325 pascals and 1 bar equals 100,000 pascals, so 1 atm = 101,325 / 100,000 = 1.01325 bar. For example, 2 atm = 2 x 1.01325 = 2.0265 bar. This calculator supports both directions: enter a bar value to get atm, or an atm value to get bar.

Bar to PSI Conversion Calculator

How many PSI is 1 bar?

1 bar equals 14.5038 PSI (pounds per square inch). This is derived from the definition: 1 bar = 100,000 pascals, and 1 PSI = 6,894.757 pascals, so 1 bar / 6,894.757 = 14.5038 PSI. For tyre pressures, if a manufacturer specifies 2.2 bar, that is approximately 31.9 PSI.

What is the formula for converting bar to PSI?

The formula is: PSI = bar x 14.5038. To convert back, PSI to bar, use: bar = PSI / 14.5038. For example, 2.5 bar x 14.5038 = 36.26 PSI. The conversion factor 14.5038 is the exact ratio of one bar (100 kPa) to one PSI (6.894757 kPa).

What is a common tyre pressure in bar and PSI?

Most passenger car tyres are inflated to between 2.0 and 2.5 bar (29 to 36 PSI). SUVs and light trucks are often set between 2.4 and 2.8 bar (35 to 41 PSI). The recommended pressure is printed on the tyre placard inside the driver's door jamb or in the owner's manual, not on the tyre sidewall (which shows the maximum pressure, not the recommended pressure).

Barometric Pressure Conversion Calculator

What is standard sea-level atmospheric pressure in different units?

Standard atmospheric pressure at sea level is defined as 101,325 Pa. This equals 1013.25 hPa (or mbar), 29.9213 inHg, 760 mmHg (Torr), 101.325 kPa, 1.01325 bar, 1 atm, and 14.6959 psi. Weather forecasters most commonly use hPa (hectopascals), which are numerically identical to millibars (mbar). Aviation uses inHg in some regions and hPa in others.

What is typical barometric pressure in New Zealand?

New Zealand sea-level barometric pressure typically ranges from about 980 hPa during deep low-pressure systems (storms) to 1035 hPa during strong high-pressure systems (settled fine weather). The long-term average is close to the global standard of 1013.25 hPa. NZ MetService reports pressure in hPa. A reading above 1020 hPa generally indicates fine weather, while readings below 1000 hPa suggest unsettled or stormy conditions.

Why do weather apps show pressure in different units?

Different regions and fields use different pressure units. Most of the world, including New Zealand, Australia, and Europe, uses hPa (hectopascals), which are equal to millibars (mbar). The United States often uses inHg (inches of mercury), especially in aviation. Scientific contexts use Pa or kPa. Medical and laboratory contexts sometimes use mmHg (millimetres of mercury, also called Torr). Bar and atm appear in engineering and chemistry. All of these units can be converted exactly using fixed multiplication factors because they all measure the same physical quantity.

Base-n Converter

How do you convert a number from one base to another?

The standard method is a two-step process. First convert the original number to base 10 (decimal) by multiplying each digit by its base raised to the power of its position, counting from the right starting at zero, and summing the results. Then convert the decimal result to the target base using repeated division: divide by the target base, record the remainder as the next digit (from right to left), and repeat with the quotient until it reaches zero.

What are the most common number bases?

The four most common bases are binary (base 2, digits 0-1, used in computing), octal (base 8, digits 0-7, used in Unix file permissions), decimal (base 10, digits 0-9, everyday arithmetic), and hexadecimal (base 16, digits 0-9 and A-F, used to represent colours and memory addresses). Higher bases up to base 36 use digits 0-9 and letters A-Z.

Why is hexadecimal used in computing?

Hexadecimal (base 16) is convenient because each hexadecimal digit maps exactly to four binary digits (bits), which matches the natural 4-bit and 8-bit groupings used in computer memory. This makes hex a compact and human-readable way to represent binary data: the byte value 11111111 in binary is FF in hexadecimal and 255 in decimal.

Billion to Trillion Converter

How many billions are in a trillion?

There are 1,000 billions in one trillion. One trillion equals 1,000,000,000,000 (10 to the power of 12), while one billion equals 1,000,000,000 (10 to the power of 9). Dividing 10^12 by 10^9 gives 10^3, which is 1,000. So to convert billions to trillions, divide by 1,000.

How do I convert 500 billion to trillions?

To convert 500 billion to trillions, divide by 1,000. 500 divided by 1,000 equals 0.5 trillion. In full, 500 billion is 500,000,000,000, which equals 0.5 trillion (or 5 x 10^11). You can verify this by multiplying back: 0.5 x 1,000 = 500 billion.

What is 1 trillion in billions?

1 trillion equals exactly 1,000 billion. A trillion is 1,000,000,000,000 (one million million), and a billion is 1,000,000,000 (one thousand million). The ratio between them is 1,000. Large sums such as national GDP or government debt are often quoted in trillions; when you see a figure such as NZD 400 billion, that is 0.4 trillion.

Binary Converter

What is binary?

Binary is the base 2 number system computers use, with only two digits, 0 and 1. Each place is a power of two, so 1011 in binary is 8 plus 0 plus 2 plus 1, which equals 11 in our usual base 10 decimal system.

How do I convert decimal to binary?

Divide the decimal number by 2 repeatedly and record the remainders, then read them from bottom to top. This tool does it instantly, and also shows the hexadecimal and octal versions, so you can convert in any direction by typing into the matching box.

What are hexadecimal and octal?

Hexadecimal is base 16, using digits 0 to 9 then A to F, and is common in computing for colours and memory addresses. Octal is base 8, using digits 0 to 7. Both are compact ways to write binary, since each hex digit is four bits and each octal digit is three.

Binary Fraction Converter

How do you convert a decimal fraction to binary?

To convert a decimal fraction (the part after the decimal point) to binary, repeatedly multiply by 2. Each time, record the integer part of the result (either 0 or 1) as the next binary digit, then continue multiplying only the remaining fractional part. Stop when the fractional part reaches 0 (exact conversion) or when you have enough precision. For example, 0.625 in decimal: 0.625 x 2 = 1.25 (record 1), 0.25 x 2 = 0.5 (record 0), 0.5 x 2 = 1.0 (record 1). Result: 0.101 in binary.

How do you convert a binary fraction to decimal?

To convert a binary fraction to decimal, each bit after the binary point represents a negative power of 2. The first bit is 2^-1 (0.5), the second is 2^-2 (0.25), the third is 2^-3 (0.125), and so on. Add the values for each bit that is 1. For example, binary 0.101 = 1 x 2^-1 + 0 x 2^-2 + 1 x 2^-3 = 0.5 + 0 + 0.125 = 0.625 in decimal.

Can all decimal fractions be exactly represented in binary?

No. Only fractions whose denominator is a power of 2 (such as 1/2, 1/4, 1/8, 3/4) can be represented exactly in binary. Fractions like 0.1 or 0.3 in decimal produce an infinitely repeating binary sequence, similar to how 1/3 produces a repeating decimal. This is why floating-point arithmetic in computers can produce small rounding errors when working with decimal numbers like 0.1. This converter limits output to 32 binary fractional digits to handle repeating cases.

Binary Hex Octal Decimal Converter

How do you convert hex FF to decimal?

FF in hexadecimal equals 255 in decimal. Each hex digit represents a power of 16: F (which equals 15) in the 16s place gives 15 times 16 = 240, and F in the 1s place gives 15. Adding them: 240 + 15 = 255. You can also use parseInt('FF', 16) in any programming language to get 255 directly.

Why is binary used in computers?

Computers use binary because digital circuits naturally represent two stable states: high voltage (1) and low voltage (0). All data, whether numbers, text, images or instructions, is ultimately stored and processed as combinations of these binary digits. Groups of 8 bits form a byte, and all higher-level data types are built from bytes.

What is the fastest way to convert binary to hex?

Group the binary digits into sets of four from right to left, padding the leftmost group with zeros if needed. Each group of four bits maps to exactly one hex digit: 0000=0, 0001=1, ..., 1001=9, 1010=A, 1011=B, 1100=C, 1101=D, 1110=E, 1111=F. For example, 11111111 groups as 1111 1111, which is FF.

Binary to Hexadecimal Converter

How do you convert binary to hexadecimal?

Group the binary digits into sets of 4, starting from the right. Pad the leftmost group with leading zeros if needed to make a full group of 4. Then convert each 4-bit group (nibble) to its hexadecimal digit: 0000=0, 0001=1, ... 1001=9, 1010=A, 1011=B, 1100=C, 1101=D, 1110=E, 1111=F. Concatenate the hex digits in order to get the result.

Why is hexadecimal useful when working with binary?

Each hexadecimal digit represents exactly 4 binary digits (one nibble), so a single hex digit is a compact shorthand for 4 bits. An 8-bit byte becomes just 2 hex digits, and a 32-bit value becomes 8 hex digits. This makes memory addresses, colour codes, and machine opcodes much easier to read and write than long strings of 0s and 1s.

What is the hexadecimal equivalent of binary 11111111?

Binary 11111111 groups into two nibbles: 1111 and 1111. Each 1111 equals F in hexadecimal. So 11111111 in binary is FF in hexadecimal, which equals 255 in decimal. FF is also the maximum value of a single byte and appears in colour codes such as #FFFFFF (white) in CSS.

Binary to Text Converter NZ

How is text stored as binary?

Each character is assigned a number by a character encoding, and that number is written in binary as a group of bits, usually eight, called a byte. For example, the capital letter H has code 72, which is 01001000 in binary. A computer stores and processes every character this way.

What is the 8-bit grouping?

Eight bits make one byte, which is enough to store one basic character. So text-to-binary writes each byte as eight binary digits, padding with leading zeros, and separates bytes with spaces. Grouping in eights makes the binary readable and reflects how memory is organised.

Does it handle emoji and accented characters?

Yes. The conversion works through UTF-8, so ordinary English characters become a single byte while accented letters, macrons and emoji become several bytes. All of them convert correctly in both directions, though multi-byte characters produce more than eight binary digits in total.

BTU/hr to Tons of Refrigeration Converter

How many BTU/hr is 1 ton of refrigeration?

One ton of refrigeration equals exactly 12,000 BTU per hour (BTU/hr). This unit originates from the amount of heat required to melt one short ton (2,000 pounds) of ice in 24 hours, which works out to 12,000 BTU/hr. So a 2-ton air conditioner has a cooling capacity of 24,000 BTU/hr, and a 5-ton unit delivers 60,000 BTU/hr.

How do I convert BTU/hr to kilowatts?

To convert BTU per hour to kilowatts, divide by 3,412.142. For example, 12,000 BTU/hr divided by 3,412.142 equals approximately 3.517 kW. To go the other way, multiply kilowatts by 3,412.142 to get BTU/hr. This conversion is based on the equivalence 1 kWh = 3,412.142 BTU.

What size air conditioner do I need for my room?

As a rough guide, you need approximately 150 to 200 BTU/hr per square metre of floor area in a standard NZ home. A 20 m2 bedroom typically requires around 3,000 to 4,000 BTU/hr (0.25 to 0.33 tons). A 40 m2 open-plan living area might need 6,000 to 9,000 BTU/hr (0.5 to 0.75 tons). Factors such as ceiling height, insulation, sun exposure, and the number of occupants all affect the required capacity. It is advisable to get a professional heat load assessment for larger installations.

Buck Converter Calculator

How do I calculate the duty cycle of a buck converter?

For an ideal buck converter the duty cycle is simply the output voltage divided by the input voltage. Stepping 12 V down to 5 V needs a duty cycle of 5 divided by 12, about 0.417 or 41.7 percent. Real converters run a slightly higher duty to make up for switch and inductor losses, but the ideal ratio is the right starting point.

How do I size the inductor for a buck converter?

Pick the inductor from the ripple current you want. The inductor ripple current equals the output voltage times the input minus output voltage, divided by the input voltage times the switching frequency times the inductance. Designers usually target a ripple of 20 to 40 percent of the maximum load current, then choose the nearest standard inductor value.

What sets the output voltage ripple?

For a buck converter the output ripple voltage is the inductor ripple current divided by eight times the switching frequency times the output capacitance, ignoring capacitor resistance. A larger output capacitor or a higher switching frequency lowers the ripple. In real designs the capacitor's equivalent series resistance often dominates the ripple.

Build Cost per Square Metre Calculator NZ

How much does it cost to build a house per square metre in NZ?

Build rates vary widely by quality, location and design, from around $2,500 per square metre for a simple build to well over $5,000 for high specification. A per-square-metre rate is a useful early ballpark, but only a builder's quote gives a firm price.

What does the per-square-metre rate include?

It usually covers the house construction itself. It often excludes the land, site works, driveways, landscaping, consents and connections, which can add a lot, so always check what a quoted rate includes.

Why add a contingency?

Builds almost always uncover surprises and changes. A contingency of around 10% to 15% on top of the base estimate gives a more realistic budget than the headline build figure alone.

Byte Conversion Calculator

How many bytes are in a megabyte?

It depends on which system you use. In the binary system used by operating systems and RAM specifications, 1 megabyte (MB) equals 1,048,576 bytes (1024 x 1024). In the decimal system used by storage manufacturers and network speeds, 1 megabyte equals exactly 1,000,000 bytes (1000 x 1000). This is why a 500 GB hard drive shows as slightly less in Windows or macOS: the OS uses binary (1 GiB = 1,073,741,824 bytes) while the manufacturer uses decimal (1 GB = 1,000,000,000 bytes).

What is the difference between MB and MiB?

MB (megabyte) and MiB (mebibyte) refer to two different amounts. The IEC introduced the mebibyte (MiB) in 1998 to remove the ambiguity: 1 MiB = 1,048,576 bytes (1024^2), while 1 MB in the decimal (SI) sense = 1,000,000 bytes (1000^2). Operating systems like Linux and macOS now use MiB for binary values, while hard drive and SSD manufacturers use MB in the decimal sense. For most everyday purposes people use MB loosely to mean either, so always check which system the context refers to.

How do I convert megabytes to megabits?

Multiply megabytes by 8 to get megabits. There are 8 bits in every byte, so 1 megabyte = 8 megabits. This conversion is the same regardless of whether you use binary or decimal megabytes. This matters for internet speeds: an ISP may quote 100 Mbps (megabits per second), which is 12.5 MB/s (megabytes per second) for file transfers. A 100 MB file would take 8 seconds to download at 100 Mbps.

Cake Pan Converter

How do I convert a recipe to a different cake pan?

Work out the base area of each tin, then divide the new area by the original area to get a scaling factor, and multiply every ingredient by it. A round tin's area is pi times the radius squared; a rectangular tin's area is length times width. Going from a 20 cm to a 23 cm round tin gives a factor of about 1.32.

Do I need to change the baking time and temperature?

Keep the oven temperature the same, but expect the baking time to change because the batter depth changes. A larger, shallower cake bakes faster, while a smaller, deeper one takes longer, so start checking a bit earlier or later and use a skewer to test for doneness.

Can I convert between round and square pans?

Yes. Because the conversion is based on area, you can mix shapes freely: choose round or rectangular for each tin and enter its dimensions. As a rough rule of thumb, a square tin holds a little more than a round tin of the same nominal size, since the corners add area.

CC to Grams Converter

Is 1 cc the same as 1 gram?

Only for pure water at 4 degrees Celsius. One cubic centimetre (1 cc) of water has a density of exactly 1 g/mL, so it weighs 1 gram. For any other substance, the mass in grams equals the volume in cc multiplied by the substance's density in g/mL. For example, 1 cc of honey weighs about 1.42 grams because honey is denser than water, while 1 cc of plain flour weighs only about 0.53 grams because flour is much less dense.

How do I convert cc to grams for cooking?

Use the formula: grams = cc x density (g/mL). For water and most thin liquids (milk, juice) the density is close to 1, so cc and grams are nearly equal. For flour, use a density of about 0.53 g/mL; for white sugar, about 0.85 g/mL; for butter, about 0.91 g/mL; and for honey, about 1.42 g/mL. Cooking densities can vary slightly depending on how loosely or firmly an ingredient is packed.

What is the difference between cc and mL?

CC (cubic centimetre) and mL (millilitre) are exactly the same unit of volume. One cc equals one mL. The term cc is more common in scientific, medical, and engineering contexts, while mL is more common in cooking and everyday use. Both measure the same quantity, so a conversion between them is always 1:1.

CC to Litre Converter

How many litres is 1 cc?

1 cubic centimetre (cc or cm³) equals exactly 0.001 litres (1 millilitre). This is because 1 litre is defined as 1,000 cubic centimetres. So to convert cc to litres, divide the number of cc by 1,000. For example, 500 cc equals 0.5 litres, and 2,500 cc equals 2.5 litres.

Is cc the same as mL?

Yes. One cubic centimetre (1 cc or 1 cm³) is exactly equal to one millilitre (1 mL). The two units are used interchangeably in medicine, cooking, and engineering. For example, a 500 cc volume is the same as 500 mL or 0.5 litres. The abbreviation 'cc' is particularly common in medical contexts (such as drug dosages and syringe measurements), while 'mL' is more common in food and beverage contexts.

How do I convert engine size from cc to litres?

To convert engine displacement from cc to litres, divide by 1,000. A 1,600 cc engine is 1.6 litres. A 2,000 cc engine is 2.0 litres. A 3,500 cc engine is 3.5 litres. Car manufacturers often round to one decimal place for marketing purposes, so a 1,998 cc engine is typically advertised as a 2.0-litre engine.

CC to mL Converter

Is 1 cc the same as 1 mL?

Yes. One cubic centimetre (cc or cm³) is exactly equal to one millilitre (mL). Both units measure the same volume. The term 'cc' is common in medicine and engineering, while 'mL' is used more widely in everyday cooking and laboratory contexts. Because 1 cm³ = 1 mL by the SI definition of the litre, there is no calculation required: 50 cc is exactly 50 mL, 250 cc is exactly 250 mL, and so on.

How many cc are in a litre?

There are exactly 1,000 cc in one litre, because 1 cc = 1 mL and 1 litre = 1,000 mL. For example, a 1.5 L bottle contains 1,500 cc, a 500 mL bottle contains 500 cc, and a standard 355 mL can contains 355 cc.

How many cc are in a fluid ounce?

One US fluid ounce equals approximately 29.5735 cc (or mL). One UK (imperial) fluid ounce equals approximately 28.4131 cc. In New Zealand, 'fluid ounce' typically refers to the US fluid ounce when used in recipes from American sources. To convert fluid ounces to cc, multiply by 29.5735.

CC to Oz Converter

How many cc are in a fluid ounce?

One US fluid ounce equals exactly 29.5735295625 cc (cubic centimetres, which are the same as millilitres). One UK imperial fluid ounce equals exactly 28.4130625 cc. Because the two systems differ by about 4 percent, it matters which ounce you are using. In everyday cooking, the difference is usually small enough to ignore, but in medical and scientific contexts you should always confirm which standard applies.

Is cc the same as mL?

Yes. One cubic centimetre (1 cc) is exactly equal to one millilitre (1 mL). Both describe the same volume: a cube with sides of one centimetre. The term cc is commonly used in medicine (for example, 5 cc syringe) and engineering, while mL is more common in everyday cooking and chemistry. You can use either label interchangeably in this converter.

How do I convert oz back to cc?

To convert US fluid ounces to cc, multiply the number of ounces by 29.5735295625. For example, 8 US fl oz equals 8 x 29.5735 = 236.59 cc (approximately 237 mL, which is close to a standard cup). To convert UK imperial fluid ounces to cc, multiply by 28.4130625. This converter includes a reverse-direction field so you can enter ounces and instantly read back the cc equivalent.

CCF to Gallons Conversion Calculator

How many gallons are in 1 CCF?

1 CCF (hundred cubic feet) equals exactly 748.052 US gallons. This is derived from the fact that 1 cubic foot = 7.48052 US gallons, and CCF is 100 cubic feet, so 100 x 7.48052 = 748.052 gallons.

What does CCF mean on a water bill?

CCF stands for hundred cubic feet (the 'C' comes from the Roman numeral for 100). It is a common unit used by US water and gas utilities to measure consumption. One CCF of water equals 748.052 US gallons, or about 2,832 litres. Many utilities charge per CCF of water used, so understanding the conversion helps you estimate your usage in more familiar units.

How do I convert CCF to litres?

To convert CCF to litres, multiply the CCF value by 2,831.685. This is because 1 cubic foot = 28.31685 litres, and 1 CCF = 100 cubic feet, so 1 CCF = 100 x 28.31685 = 2,831.685 litres. Alternatively, convert to US gallons first (multiply by 748.052), then multiply by 3.78541 to get litres.

Celsius Converter

What is the formula to convert Celsius to Fahrenheit?

The formula to convert Celsius (°C) to Fahrenheit (°F) is: F = (C × 9/5) + 32. For example, 100°C equals (100 × 1.8) + 32 = 180 + 32 = 212°F, which is the boiling point of water at sea level. To go the other way, from Fahrenheit to Celsius, use: C = (F - 32) × 5/9.

How do you convert Celsius to Kelvin?

To convert Celsius to Kelvin (K), simply add 273.15: K = C + 273.15. For example, 0°C (the freezing point of water) equals 273.15 K. Absolute zero, the coldest possible temperature, is 0 K, which equals -273.15°C. Kelvin uses the same scale intervals as Celsius but starts at absolute zero, so no degree symbol is used with Kelvin.

What is the difference between Celsius and Fahrenheit?

Celsius and Fahrenheit are both temperature scales, but they use different reference points and intervals. On the Celsius scale, 0°C is the freezing point of water and 100°C is the boiling point at sea level. On the Fahrenheit scale, those same points are 32°F and 212°F. The scales cross at -40° (that is, -40°C equals -40°F). Celsius is used in most of the world including New Zealand. Fahrenheit is used mainly in the United States.

Celsius to Fahrenheit Converter

What is the formula to convert Celsius to Fahrenheit?

The formula is F = (C x 9/5) + 32, where C is the temperature in Celsius and F is the result in Fahrenheit. For example, 100 degrees Celsius equals (100 x 9/5) + 32 = 180 + 32 = 212 degrees Fahrenheit. To convert in the other direction, use C = (F - 32) x 5/9.

At what temperature are Celsius and Fahrenheit the same?

Celsius and Fahrenheit are equal at negative 40 degrees. That is, -40 degrees Celsius equals -40 degrees Fahrenheit. This is the only point where the two scales intersect. You can verify this using the formula: F = (-40 x 9/5) + 32 = -72 + 32 = -40.

What are some useful Celsius to Fahrenheit reference temperatures?

Common reference temperatures include: 0 degrees Celsius (water freezes) = 32 degrees Fahrenheit; 20 degrees Celsius (comfortable room temperature) = 68 degrees Fahrenheit; 37 degrees Celsius (normal human body temperature) = 98.6 degrees Fahrenheit; 100 degrees Celsius (water boils at sea level) = 212 degrees Fahrenheit. For a quick mental estimate, double the Celsius temperature and add 30 to get an approximate Fahrenheit value.

Cent to Square Metre Converter

How many square metres are in one cent?

One cent equals 40.4686 square metres. This is because one cent is defined as one hundredth of an acre, and one acre equals 4,046.86 square metres. So 1 cent = 4046.86 ÷ 100 = 40.4686 m². For practical purposes this is often rounded to 40.47 m².

Where is the cent used as a unit of land measurement?

The cent is commonly used in southern India (particularly Tamil Nadu, Kerala, Andhra Pradesh, and Karnataka), Sri Lanka, and some parts of Bangladesh and Malaysia to measure residential and agricultural land plots. It is also used by some South Asian communities in New Zealand and Australia when describing inherited or overseas land. In these regions, land is often described in terms of cents and grounds rather than in square metres or hectares.

How do I convert square metres back to cents?

To convert square metres to cents, divide the number of square metres by 40.4686. For example, 200 m² ÷ 40.4686 = 4.942 cents. This converter performs the calculation in both directions. You can enter a value in cents to get square metres, or enter square metres to get cents.

cm to mm Converter

How many millimetres are in a centimetre?

There are exactly 10 millimetres in one centimetre. Both units are part of the International System of Units (SI). The centimetre is defined as one hundredth of a metre, and the millimetre is one thousandth of a metre, so a centimetre is always exactly 10 millimetres. To convert cm to mm, multiply by 10. To convert mm to cm, divide by 10.

How do I convert cm to mm?

To convert centimetres to millimetres, multiply the number of centimetres by 10. For example: 5 cm = 5 x 10 = 50 mm. 12.5 cm = 12.5 x 10 = 125 mm. 0.8 cm = 0.8 x 10 = 8 mm. The conversion is exact because both units are defined within the SI metric system.

When would I use mm instead of cm?

Millimetres are preferred for small, precise measurements where fractions of a centimetre matter. Engineering drawings, joinery, cabinetmaking, plumbing fittings, and medical measurements typically use millimetres to avoid decimal fractions. For example, a 15 mm pipe fitting is clearer than 1.5 cm. Centimetres are more commonly used for everyday body measurements, clothing sizes, and distances that do not require fine precision.

cm to mm Ring Size Converter

How do I convert centimetres to millimetres for ring sizing?

Multiply your finger circumference in centimetres by 10 to get millimetres. For example, 5.0 cm equals 50 mm. The EU/ISO ring size system uses circumference in millimetres directly, so a 50 mm circumference corresponds to EU ring size 50. For US, UK/NZ/AU, and Japanese sizes you then look up the mm value in the relevant conversion chart, as each system uses a different scale and starting point.

What ring size is 5 cm circumference?

A finger circumference of 5.0 cm (50 mm) gives: EU/ISO size 50, US/Canada size approximately 5.5, UK/NZ/AU size approximately K to K1/2, and Japanese size approximately 10. The diameter at 50 mm circumference is approximately 15.9 mm. If you are between sizes, it is generally better to choose the larger size for comfort, especially in warmer weather when fingers swell slightly.

Which ring sizing system does New Zealand use?

New Zealand uses the UK/AU/NZ/SA system, which sizes rings with alphabet letters from A to Z and then Z1, Z2, and so on. Each full letter represents a circumference increment of approximately 1.25 mm and a diameter increment of about 0.4 mm. Many NZ jewellers also refer to EU sizes (circumference in mm) as a universal reference. When ordering rings online from international retailers, always confirm which sizing system the retailer uses and convert accordingly.

cm to Ring Size Converter

How do I measure my finger circumference in cm?

Wrap a thin strip of paper or a piece of string around the base of the finger you want to measure. Mark where the paper or string overlaps, then lay it flat against a ruler and read the length in centimetres. That measurement is your finger circumference. For the most accurate result, measure in the evening when fingers tend to be slightly larger, and measure the finger you plan to wear the ring on. A circumference of around 5.5 cm is a common starting point for many adults (roughly a size L in NZ/UK or a US size 6).

What ring size system does New Zealand use?

New Zealand, Australia, and the United Kingdom all use the same letter-based ring sizing system derived from British Standard BS 1927. Sizes run alphabetically from A (smallest, approximately 37.8 mm circumference) up through to Z and beyond (Z+1, Z+2, etc. for larger sizes). Each full letter size represents approximately 1.25 mm increase in inner circumference, with half sizes about 0.6 mm apart. Most jewellers in NZ carry sizes F through T as standard stock, with sizes outside that range available to order.

How does the EU/ISO ring size system work?

The EU/ISO ring size (also used in France, Germany, Spain, Italy, and other European countries) is simply the inner circumference of the ring in millimetres, rounded to the nearest half millimetre. So a finger circumference of 5.2 cm equals 52 mm, which is an EU size 52. This makes EU sizing very straightforward to work with: your finger circumference in mm equals your EU ring size. The EU system is also used in China and Japan (with a slightly different number offset for Japanese sizes).

Color Converter: HEX, RGB, HSL

What is the difference between HEX, RGB, and HSL colour codes?

HEX (hexadecimal) is a six-character code like #3b82f6 that represents the red, green, and blue channels as two-digit hex pairs. RGB stands for Red, Green, Blue and expresses each channel as a number from 0 to 255, for example rgb(59, 130, 246). HSL stands for Hue, Saturation, Lightness: hue is a degree from 0 to 360 on the colour wheel, saturation is a percentage of colour intensity, and lightness is a percentage from black (0%) to white (100%). All three formats describe exactly the same colour space; HSL is often more intuitive for designers because you can adjust brightness and saturation independently.

How do you convert HEX to RGB?

Split the six-character HEX string into three pairs (RR, GG, BB) and convert each pair from base-16 (hexadecimal) to base-10 (decimal). For example, #3b82f6 splits into 3b, 82, and f6. In decimal: 3b = 3x16+11 = 59, 82 = 8x16+2 = 130, f6 = 15x16+6 = 246. So #3b82f6 is rgb(59, 130, 246). Short three-character HEX codes like #39f expand each digit by doubling it: #39f becomes #3399ff.

How do you convert RGB to HSL?

Normalise R, G, B to the range 0 to 1 by dividing each by 255. Find the maximum (Cmax) and minimum (Cmin) of the three values. Lightness L = (Cmax + Cmin) / 2. If Cmax equals Cmin, saturation S is 0 and hue H is 0 (achromatic grey). Otherwise, the chroma C = Cmax - Cmin, saturation S = C / (1 - |2L - 1|). Hue H depends on which channel is the maximum: if red is max, H = 60 x ((G - B) / C mod 6); if green is max, H = 60 x ((B - R) / C + 2); if blue is max, H = 60 x ((R - G) / C + 4). A negative H is adjusted by adding 360.

Conversion Funnel Calculator

How do you calculate the conversion rate between two funnel stages?

The conversion rate between two consecutive funnel stages is calculated as: CVR = (Stage B visitors / Stage A visitors) x 100. For example, if 1,000 people visit your product page (Stage A) and 250 add to cart (Stage B), the step conversion rate is (250 / 1000) x 100 = 25%. The drop-off count is Stage A minus Stage B (750 people in this case), and the drop-off percentage is 100 minus the conversion rate (75%).

What is overall funnel conversion rate?

The overall funnel conversion rate is the percentage of people who entered the top of the funnel and made it all the way to the final stage: Overall CVR = (Final stage count / Top of funnel count) x 100. For a funnel with 10,000 visitors at the top and 120 customers at the bottom, the overall CVR is (120 / 10,000) x 100 = 1.2%. This is distinct from the step-by-step conversion rates, which measure progress between adjacent stages.

How many stages should a conversion funnel have?

Most marketing and e-commerce funnels use three to six stages. A simple funnel might be Awareness, Consideration, Purchase. An e-commerce funnel often includes Product View, Add to Cart, Checkout Start, and Payment Complete. A sales funnel might use Lead, Qualified Lead, Proposal, Closed Won. The right number of stages depends on your process: each stage should represent a meaningful decision or action taken by the customer. Tracking too many stages can create noise; too few hides where people are dropping off.

Cooking Measurement Converter

How many mL is a cup?

A US legal cup equals 240 mL exactly. A US customary cup equals 236.588 mL. Most recipes and this converter use the US customary cup of 236.588 mL, which is the most common definition in cookbooks and recipe websites. An Australian metric cup is 250 mL and an Imperial cup is 284.131 mL.

How many teaspoons are in a tablespoon?

There are 3 teaspoons in one tablespoon, by standard definition in the US, Australia, and most other countries. One US tablespoon equals 14.787 mL and one US teaspoon equals 4.929 mL. In Australia, one tablespoon is 20 mL (4 teaspoons), so check your recipe's origin if precision matters.

How do I convert US fluid ounces to millilitres?

One US fluid ounce equals 29.5735 mL. To convert, multiply the number of fluid ounces by 29.5735. Note that a UK fluid ounce is slightly larger at 28.4131 mL. Recipes from the United States use the US fluid ounce, while UK recipes use the Imperial fluid ounce.

Coordinates Converter

What is the difference between decimal degrees and DMS?

Decimal degrees write a coordinate as a single number, such as -41.2865. DMS splits it into degrees, minutes, and seconds, such as 41 degrees, 17 minutes, 11 seconds south. Both describe the same point, but different apps and maps prefer different formats.

How do I convert decimal degrees to DMS?

The whole number is the degrees. Multiply the decimal part by 60 to get the minutes, take the whole minutes, then multiply that leftover by 60 again for the seconds. The sign tells you the hemisphere, with negative meaning south or west.

Are New Zealand coordinates negative?

Latitudes in New Zealand are negative because the country is in the southern hemisphere, for example about -41 for Wellington. Longitudes are positive because New Zealand is east of the prime meridian, around 174. The converter keeps the sign so the hemisphere stays correct.

Cost Per Mile Calculator

How do I calculate cost per mile?

Cost per mile = Total cost divided by total miles travelled. For example, if a trip costs $45 and covers 150 miles, the cost per mile is $45 / 150 = $0.30 per mile. Include all relevant costs such as fuel, tolls, and parking in your total to get a true per-mile figure.

What costs should I include when calculating cost per mile?

For a single trip, include fuel, tolls, parking, and any other out-of-pocket expenses. For a full vehicle cost-per-mile calculation, you can also include registration, insurance, tyres, servicing, and depreciation spread across your annual mileage. The more costs you include, the more accurate your true cost per mile will be.

How do I convert cost per mile to cost per km?

One mile equals 1.60934 kilometres. To convert cost per mile to cost per km, divide the cost per mile by 1.60934. For example, $0.30 per mile equals $0.30 / 1.60934 = $0.186 per km. This calculator does this conversion automatically.

Crore to Lakh Converter

How many lakhs are in one crore?

There are exactly 100 lakhs in one crore. This relationship is fixed in the South Asian numbering system: 1 lakh = 100,000 (one hundred thousand) and 1 crore = 10,000,000 (ten million). So 1 crore divided by 1 lakh equals 100. For example, 5 crore equals 500 lakh, and 2.5 crore equals 250 lakh.

How do I convert crore to lakh?

To convert crores to lakhs, multiply the number of crores by 100. The formula is: Lakhs = Crores x 100. For example, 3 crore x 100 = 300 lakh. To convert in the opposite direction, from lakhs to crores, divide by 100: Crores = Lakhs / 100.

How does the crore and lakh system relate to millions and billions?

The South Asian numbering system uses lakhs and crores instead of the Western millions and billions. 1 lakh equals 100,000 (0.1 million). 1 crore equals 10,000,000 (10 million). Therefore, 10 crore equals 100 million, and 100 crore equals 1 billion. The crore and lakh system is widely used in India, Pakistan, Bangladesh, Nepal, and Sri Lanka for financial and population figures.

Crore to Million Converter

How many millions is 1 crore?

1 crore equals 10 million. A crore is a unit of the South Asian numbering system equal to 10,000,000 (ten million). So 1 crore = 10 million, 2 crores = 20 million, 5 crores = 50 million, and 10 crores = 100 million (1 billion in the Western system).

How do you convert crores to millions?

To convert crores to millions, multiply the number of crores by 10. For example, 3.5 crores multiplied by 10 equals 35 million. To convert in the opposite direction, from millions to crores, divide by 10. For example, 250 million divided by 10 equals 25 crores.

How does the crore system relate to the Western numbering system?

The crore is part of the South Asian numbering system used in India, Pakistan, Bangladesh, Nepal, and Sri Lanka. In that system, 1 lakh equals 100,000 and 1 crore equals 100 lakhs, or 10,000,000. In the Western system, this is simply 10 million. Ten crores equals 100 million, which is one-tenth of a billion in Western usage. The South Asian system groups digits in twos after the first three, whereas the Western system groups in threes throughout.

Cross-Lease to Freehold Conversion Cost Calculator NZ

Why convert a cross-lease to freehold?

A freehold (fee simple) title is simpler, usually worth more, and removes the shared-ownership headaches of a cross-lease, such as needing neighbours' consent for alterations and keeping the flats plan up to date. Many owners convert to lift value and make the property easier to sell.

Do all the cross-lease owners have to agree?

Yes. Because the owners jointly own the land, converting to freehold is effectively a subdivision that needs every cross-lease owner to take part. The cost is usually shared between them, which is why this tool shows both the total and your share.

How much does conversion cost?

It varies widely with the property and council, but survey, legal, council consent and LINZ registration commonly run into the tens of thousands in total. Split between two or three owners, your share is lower. Always get quotes for your situation.

CSS Unit Converter: px, em, rem

What is the difference between px, em, and rem in CSS?

px (pixels) is an absolute unit that always renders at the same physical size regardless of context. em is a relative unit scaled to the font size of the element's parent: if a parent has font-size 16px, then 1.5em in a child equals 24px. rem (root em) is also relative but always scales to the root element (html) font size, which browsers default to 16px. Because rem ignores nesting, it is more predictable than em for layout and typography across complex page structures.

Why do browsers default to 16px?

The default root font size of 16px is a convention set by browser vendors and formalised in the CSS specification. It dates to early typographic standards where 16px was considered a comfortable reading size on typical monitor resolutions. You can override it by setting font-size on the html element (for example, html { font-size: 18px; }), which then changes the scale of all rem values across your page.

Should I use em or rem for responsive design?

rem is generally preferred for font sizes and spacing in modern responsive design because it scales predictably from a single root value. A user increasing their browser base font size will see all rem-based layouts scale correctly. em is useful for component-relative sizing, for example setting padding as a fraction of the component's own font size so spacing scales naturally with the text. Many design systems use rem for global rhythm and em for local component relationships.

CSV to JSON Converter NZ

How do I convert CSV to JSON?

Make sure the first row holds the column names, then paste the CSV here. The tool uses the headers as keys and turns each row into a JSON object, collecting them into an array. The formatted JSON appears ready to copy into your code or tools.

Does my data get uploaded?

No. The conversion runs entirely in your browser using JavaScript, so your CSV never leaves your device. This makes it safe to convert sensitive or private data, which you should not paste into tools that send data to a server.

What about commas inside fields?

This converter splits on every comma, which works perfectly for clean CSV without commas inside values. If your data has commas within quoted fields, those need a fuller CSV parser that understands quoting, since a simple split would break such rows into the wrong columns.

Cubic Feet to Cubic Metres Converter

How many cubic metres are in a cubic foot?

One cubic foot equals exactly 0.028316846592 cubic metres (m³). This is derived from the international yard definition: 1 foot = 0.3048 metres exactly, so 1 ft³ = 0.3048³ = 0.028316846592 m³. For most practical purposes 0.02832 m³ is sufficiently precise.

How do I convert cubic feet to cubic metres?

Multiply the number of cubic feet by 0.028316846592. For example, 10 ft³ × 0.028316846592 = 0.2832 m³. To go the other way, multiply cubic metres by 35.3147 to get cubic feet.

Why do cubic unit conversions differ from linear ones?

Because volume is three-dimensional, the linear conversion factor is cubed. One foot is 0.3048 metres, but one cubic foot is 0.3048³ = 0.028317 m³, not simply 0.3048 m³. Similarly, one square foot is 0.3048² = 0.0929 m². Always cube the linear factor when converting volumes.

Cubic Feet to Pounds Calculator

How do you convert cubic feet to pounds?

You cannot convert cubic feet to pounds without knowing the density of the material, because cubic feet measures volume while pounds measures weight (mass). The formula is: Weight (lb) = Volume (ft³) x Density (lb/ft³). For example, water has a density of approximately 62.43 lb/ft³, so 5 cubic feet of water weighs 5 x 62.43 = 312.15 lb. Different materials have very different densities: concrete is about 150 lb/ft³, dry sand is about 100 lb/ft³, and pine timber is about 31 lb/ft³.

How many pounds is 1 cubic foot of water?

One cubic foot of water weighs approximately 62.43 pounds (or 28.32 kg) at standard temperature (4°C / 39°F). This is the most common reference density for volume-to-weight conversions. At typical room temperature (20°C), water is slightly less dense at about 62.30 lb/ft³, but 62.43 lb/ft³ is the standard figure used in most calculations.

How many pounds is 1 cubic foot of concrete?

One cubic foot of standard ready-mix concrete weighs approximately 150 pounds (68 kg). This figure is used in most structural engineering calculations. Lightweight concrete can weigh as little as 90 lb/ft³, and high-density concrete used for radiation shielding can exceed 200 lb/ft³. The standard 150 lb/ft³ (2,400 kg/m³) figure applies to normal-weight concrete made with sand, gravel, and Portland cement.

Cubic Inches to Gallons Converter

How many cubic inches are in a US gallon?

There are exactly 231 cubic inches in one US liquid gallon. This is the statutory definition established in the US Weights and Measures Act. To convert cubic inches to US gallons, divide the number of cubic inches by 231. For example, 462 cubic inches equals 2 US gallons.

How many cubic inches are in a UK (Imperial) gallon?

One UK (Imperial) gallon equals approximately 277.419 cubic inches. The UK gallon is defined as exactly 4.54609 litres, which converts to approximately 277.4194 cubic inches. The UK gallon is about 20 percent larger than the US liquid gallon. To convert cubic inches to UK gallons, divide by 277.419.

Why are US and UK gallons different sizes?

The US and UK gallon diverged historically. The US gallon is based on the old English wine gallon of 231 cubic inches, which was the standard before the UK redefined its gallon in the Weights and Measures Act 1824. The UK Imperial gallon was redefined as the volume of ten pounds of water at a specific temperature and pressure, which works out to about 277.42 cubic inches. As a result, one UK gallon is approximately 1.2009 US gallons.

Cubic Metre Calculator (CBM)

How do I calculate cubic metres?

Multiply length by width by height, with all three in metres. If your measurements are in centimetres, multiply them and divide by 1,000,000, because there are 1,000,000 cubic centimetres in a cubic metre.

What is CBM?

CBM stands for cubic metre, the standard unit of volume used in shipping and freight. Carriers price sea and air freight partly on CBM, so knowing the cubic metres of your cartons helps you estimate freight cost and how much will fit in a container.

How do I find the total CBM for several boxes?

Work out the cubic metres of one box, then multiply by the number of identical boxes. Enter a quantity above and the calculator shows both the volume per item and the total volume.

Cubic Metre to Tonne Converter

How do I convert cubic metres to tonnes?

Multiply the volume in cubic metres by the material's density in tonnes per cubic metre (t/m³). For example, 5 m³ of concrete at 2.4 t/m³ equals 12 tonnes. The density varies significantly by material: water is 1.0 t/m³, concrete is about 2.4 t/m³, steel is about 7.85 t/m³, and dry sand is about 1.6 t/m³. Always confirm the exact density with your supplier for critical applications.

How many tonnes is 1 cubic metre of concrete?

One cubic metre of normal-strength concrete weighs approximately 2.4 tonnes (2,400 kg). This figure is the standard bulk density used in structural calculations. Lightweight concrete can be as low as 1.4 t/m³ and high-density concrete can exceed 3.0 t/m³. For most standard residential and commercial pours, 2.4 t/m³ is the accepted value.

Is a metric tonne the same as a ton?

No. A metric tonne (t) is 1,000 kilograms. A short ton (used in the United States) is 2,000 pounds, which equals approximately 907 kg. A long ton (used in the United Kingdom historically) is 2,240 pounds, or about 1,016 kg. In New Zealand and Australia, 'tonne' always refers to the metric tonne of 1,000 kg. This converter uses metric tonnes throughout.

Cubic Yards to Tons Calculator

How many tons is a cubic yard of gravel?

One cubic yard of gravel (crushed stone) weighs approximately 1.35 short tons (about 1.22 metric tonnes). The exact weight depends on the type of gravel and how dry or compacted it is. Pea gravel tends to be lighter at around 1.25 tons per cubic yard, while dense crushed rock can reach 1.45 tons. For ordering purposes, 1.35 tons per cubic yard is a reliable working figure for most gravel and crushed stone.

How do I convert cubic yards to tons for soil or topsoil?

To convert cubic yards to tons for topsoil, multiply the number of cubic yards by approximately 1.10 (short tons per cubic yard). For example, 5 cubic yards of topsoil weighs around 5.5 short tons (5.0 metric tonnes). Note that topsoil weight varies with moisture content: dry topsoil is lighter, and wet or clay-rich topsoil can weigh closer to 1.30 to 1.50 tons per cubic yard. The figure of 1.10 tons per cubic yard is a typical value for dry, loose topsoil.

What is the difference between a short ton and a metric tonne?

A short ton (used mainly in the United States) equals 2,000 pounds (approximately 907 kg). A metric tonne equals 1,000 kg (approximately 2,205 pounds). To convert short tons to metric tonnes, multiply by 0.9072. To convert metric tonnes to short tons, multiply by 1.1023. In New Zealand, weights are measured in metric tonnes; however, cubic yards and short tons are still commonly referenced in international material specifications, so it is useful to see both.

Cups to Gallons Converter

How many cups are in a gallon?

There are 16 US cups in 1 US gallon. Each US cup holds 236.588 mL and a US gallon holds 3,785.41 mL (3.785 litres). In the UK system, 1 UK gallon equals approximately 16 UK cups, since a UK cup is 284.131 mL and a UK gallon is 4,546.09 mL. However, UK cups are not as commonly used in recipes as US cups.

How do I convert cups to gallons?

To convert US cups to US gallons, divide the number of cups by 16. For example, 8 cups divided by 16 equals 0.5 gallons (half a gallon). To convert gallons back to cups, multiply by 16. For UK measurements, divide UK cups by 16 to get UK gallons, as the ratio is the same (a UK imperial cup is defined as half an imperial pint, which is 10 imperial fluid ounces, and there are 8 pints in an imperial gallon, so there are 16 cups per gallon).

Is a US gallon the same as a UK gallon?

No. A US gallon is 3,785.41 mL (approximately 3.785 litres), while a UK imperial gallon is 4,546.09 mL (approximately 4.546 litres). A UK gallon is about 20 percent larger than a US gallon. If you are following a US recipe using US cups, use the US gallon conversion. If you are working with UK or imperial measurements, use the UK gallon.

Cups to Ounces (oz) Converter

How many fluid ounces are in a US cup?

One US customary cup equals exactly 8 US fluid ounces (fl oz), which is 236.588 ml. This is the standard cup size used in most American recipes and the most widely recognised cup measurement internationally.

Is a cup 8 oz or 16 oz?

A standard US cup is 8 fluid ounces. A 16 fl oz measurement is equal to 2 cups (often called a pint in US measure). Confusion sometimes arises with dry weight ounces: 1 cup of water weighs approximately 8.33 weight ounces, while 1 cup of flour weighs around 4.25 weight ounces because the weight depends on what is being measured.

How many ounces are in a metric cup?

A metric cup, used in Australia, New Zealand, and Canada, equals 250 ml. This is approximately 8.45 US fluid ounces, or 8.80 UK fluid ounces. The metric cup is slightly larger than the US customary cup (236.588 ml) but smaller than the UK imperial cup (284.131 ml / 10 fl oz).

Cups to Pints Converter

How many cups are in a pint?

There are 2 US cups in 1 US pint. A US cup is 236.588 mL and a US pint (16 fl oz) is 473.176 mL, so the ratio is exact: 2 cups always equals 1 pint in the US system. The imperial (UK) system also gives 2 cups per pint, because an imperial cup is 284.131 mL, exactly half of an imperial pint (568.261 mL), based on the old 10 fl oz imperial cup definition. The ratio only changes when you mix systems: an imperial pint holds about 2.4 US cups, since a US cup is smaller.

Is a New Zealand cup the same as a US cup?

No. New Zealand and Australia use a metric cup of exactly 250 mL, while the US customary cup is 236.588 mL (about 5.4 percent smaller). Recipes from US sources use the US cup unless stated otherwise. This converter lets you choose which cup definition you are working with (US, metric/NZ, or imperial) so your pint conversion is accurate for the recipe you are following.

How do I convert pints to millilitres?

Multiply the number of pints by the pint size you are using: 473.176 mL for a US pint, or 568.26 mL for an imperial (UK) pint. For example, 1.5 US pints equals 1.5 times 473.176, which is about 709.76 mL. New Zealand recipes and packaging almost always use millilitres or litres directly, so converting from pints is mainly useful when following older British or American recipes and measurements.

Cups to Pounds Converter

How many pounds are in a cup?

It depends entirely on the ingredient, because a cup is a fixed volume (250 mL for a NZ metric cup) but the weight of that volume changes with density. A cup of water weighs about 0.551 lb (250 g). A cup of plain flour weighs about 0.276 lb (125 g), while a cup of white sugar weighs about 0.485 lb (220 g). There is no single conversion between cups and pounds without knowing what you are measuring.

How do you convert cups to pounds?

First find the reference weight in grams for one cup of your ingredient (this varies by ingredient density). Multiply that by the number of cups to get the total grams, then divide by 453.592 to convert grams to pounds. The formula is: Pounds = (Cups x grams per cup) / 453.592. For example, 2 cups of plain flour: 2 x 125 g = 250 g, and 250 / 453.592 = 0.551 lb.

Is a US cup the same weight in pounds as a NZ cup?

No. A NZ/Australian metric cup is 250 mL while a US customary cup is approximately 236.6 mL (often rounded to 240 mL). Since a US cup holds about 5 to 6 percent less volume, the same ingredient measured in a US cup weighs slightly less in pounds than when measured in a NZ metric cup. This converter lets you choose the correct cup size for accurate results.

Cups to Quarts Converter

How many cups are in a quart?

There are 4 US cups in 1 US liquid quart. This is because 1 quart equals 2 pints, and each pint equals 2 cups (2 x 2 = 4). So 1 cup equals a quarter (0.25) of a quart, which is where the word 'quart' comes from.

How do I convert cups to quarts?

Divide the number of cups by 4 to get quarts. For example, 8 cups divided by 4 equals 2 quarts. To convert quarts back to cups, multiply the number of quarts by 4. For example, 3 quarts multiplied by 4 equals 12 cups.

Is a US quart the same as a UK or NZ quart?

No. This converter uses US customary units, which are standard in most recipes online. A US quart is about 946 ml, while an imperial quart (used historically in the UK and NZ) is about 1,136 ml, roughly 20 percent larger. New Zealand now uses the metric system for cooking, so recipes here are usually given in millilitres or litres rather than quarts.

Current Converter

How many milliamps are in an amp?

There are exactly 1,000 milliamps in one ampere. The prefix milli means one thousandth, so 1 mA is 0.001 A. This is an exact definition under the SI system rather than a measured conversion, so no rounding error is introduced.

What is the difference between mA and uA?

A milliamp is one thousandth of an amp and a microamp is one millionth, so one milliamp equals 1,000 microamps. Milliamps are the usual unit for the running current of small electronics, while microamps are used for sleep or standby currents in battery-powered devices.

Can current be negative?

Yes. A negative value simply means the current flows in the opposite direction to the reference you chose. The magnitude converts in exactly the same way, so a reading of minus 250 mA is minus 0.25 A.

Cylinder Volume Calculator (Litres, US and Imperial Gallons)

What is the formula for cylinder volume?

The volume of a cylinder is V = pi times r squared times h, where r is the radius of the circular base and h is the height (or length, if the cylinder is lying on its side). If you only know the diameter, divide it by two to get the radius before applying the formula. The result is in cubic units matching whatever unit you measured radius and height in, for example cubic metres if you measured in metres.

How do you convert cylinder volume to litres or gallons?

One litre equals 1,000 cubic centimetres, or 0.001 cubic metres. So a volume in cubic metres multiplied by 1,000 gives litres. To convert litres to US gallons, divide by 3.785411784. To convert litres to imperial (UK) gallons, divide by 4.54609. These are the standard conversion factors used worldwide, including in New Zealand, which uses litres as its everyday liquid volume unit.

Does it matter if the cylinder is standing up or lying on its side?

No, total volume is the same either way because volume only depends on the radius of the circular cross-section and the overall length along the cylinder's axis. Orientation only matters if you need the volume of liquid at a partial fill level, which requires a different, more complex partial-volume formula for a horizontal cylinder.

Data Storage Converter

Why does my 1 TB hard drive show less space in Windows?

Hard drive manufacturers use SI decimal definitions where 1 TB = 1,000,000,000,000 bytes (10^12). Windows reports storage using binary definitions where 1 TiB = 1,099,511,627,776 bytes (2^40). So a 1 TB drive contains about 931 GiB as reported by Windows. The actual storage capacity is unchanged; only the labelling convention differs.

What is the difference between GB and GiB?

GB (gigabyte) in the SI system equals 1,000,000,000 bytes (10^9). GiB (gibibyte) in the IEC binary system equals 1,073,741,824 bytes (2^30). One GiB is about 7.37 percent larger than one GB. Storage manufacturers use GB; operating systems like Windows traditionally use GiB but label them GB, which causes the apparent discrepancy.

How many bits are in a byte?

There are 8 bits in one byte, by universal definition. This relationship is constant across both SI and binary systems. A kilobit (kbit) therefore equals 125 bytes, and a megabit (Mbit) equals 125,000 bytes. Internet speeds are often quoted in megabits per second (Mbps) rather than megabytes, so a 100 Mbps connection downloads at roughly 12.5 MB/s.

Data Transfer Rate Converter

How do you convert Mbps to MB/s?

Divide megabits per second by 8 to get megabytes per second, because there are 8 bits in one byte. For example, 100 Mbps divided by 8 equals 12.5 MB/s. This is why a 100 Mbps broadband plan downloads files at about 12 megabytes per second, not 100 megabytes per second.

What is the difference between Mbps and MB/s?

Mbps is megabits per second: the M stands for mega (10 to the 6), b means bits, and ps means per second. MB/s is megabytes per second: the B is uppercase for bytes. One byte equals 8 bits, so MB/s = Mbps divided by 8. Internet speeds are usually advertised in Mbps; file download progress is usually shown in MB/s.

What is the difference between Mbps (SI) and Mibps (IEC binary)?

In the SI (decimal) system, 1 Mbps = 1,000,000 bits per second (1 million). In the IEC binary system, 1 Mibps = 1,048,576 bits per second (2 to the power of 20). The IEC prefixes (kibi-, mebi-, gibi-) were introduced to eliminate ambiguity. Network speeds almost always use SI (decimal) prefixes; RAM and some file sizes use IEC binary.

Decimal Degrees to DMS Converter

How do you convert decimal degrees to degrees, minutes and seconds?

Take the whole number part of the decimal degrees value as the degrees. Multiply the remaining decimal fraction by 60 to get minutes. Take the whole number part of that as the minutes, then multiply the new remaining fraction by 60 to get seconds. For example, 41.40338 degrees splits into 41 degrees, then 0.40338 x 60 = 24.2028 minutes, so 24 minutes, then 0.2028 x 60 = 12.168 seconds. The result is 41 degrees, 24 minutes, 12.17 seconds.

How do you convert degrees, minutes and seconds back to decimal degrees?

Divide the minutes by 60 and the seconds by 3600, then add both to the degrees. The formula is decimal degrees = degrees + (minutes / 60) + (seconds / 3600). For example, 41 degrees, 24 minutes, 12.17 seconds converts to 41 + (24/60) + (12.17/3600) = 41 + 0.4 + 0.00338 = 41.40338 decimal degrees.

Why do GPS coordinates sometimes use decimal degrees and sometimes DMS?

Decimal degrees (for example -41.2865, 174.7762) are the standard format for digital mapping, GPS devices, and software such as Google Maps, because they are simpler to store and calculate with. Degrees, minutes and seconds (for example 41 degrees 17 minutes 11.4 seconds S) is the traditional format used in navigation, surveying, and older maps, and is still common on nautical charts and legal land descriptions in New Zealand.

Decimal Time Converter

What is decimal time?

Decimal time expresses minutes as a fraction of an hour rather than out of 60. So 1 hour 30 minutes becomes 1.5 hours, and 1 hour 15 minutes becomes 1.25 hours. Payroll and billing systems usually need decimal hours to multiply by an hourly rate.

How do I convert minutes to decimal?

Divide the minutes by 60. So 30 minutes is 30 divided by 60, which is 0.5, and 45 minutes is 0.75. Add that to the whole hours. This converter does it both ways, so you can also turn decimal hours back into hours and minutes.

Why does payroll use decimal hours?

Because pay is an hourly rate times hours worked, and you cannot multiply cleanly by minutes out of 60. Converting 7 hours 30 minutes to 7.5 hours lets you multiply directly by the rate. Getting this wrong is a common cause of small payroll errors.

Decimal to Hexadecimal Converter

How do you convert decimal to hexadecimal?

Divide the decimal number by 16 repeatedly, recording the remainder each time. Convert each remainder to a hex digit (0-9 stay the same, 10-15 become A-F). Read the remainders in reverse order (last remainder first) to get the hexadecimal result. For example, 255 divided by 16 is 15 remainder 15 (F), then 15 divided by 16 is 0 remainder 15 (F), giving FF.

Why does hexadecimal use letters A to F?

Hexadecimal is base 16, which needs 16 distinct digit symbols. The digits 0 to 9 only provide 10 symbols, so hexadecimal borrows the letters A, B, C, D, E and F to represent the values 10, 11, 12, 13, 14 and 15. This lets a single hex digit represent any value from 0 to 15, which conveniently matches exactly 4 binary bits (a nibble).

Where is hexadecimal used in computing?

Hexadecimal is widely used because each hex digit maps exactly to 4 binary bits, making it a compact, human readable way to represent binary data. Common uses include colour codes in web design (such as #FF5733), memory addresses, MAC addresses, byte values in programming and debugging, and Unicode character codes.

Decimal to Percent Converter

How do you convert a decimal to a percent?

Multiply the decimal by 100 and add a percent sign. For example, 0.25 multiplied by 100 equals 25, so 0.25 as a percentage is 25%. This works because a percentage is simply a number expressed as a fraction of 100, and multiplying by 100 converts the decimal fraction into that same scale.

What is 0.5 as a percentage?

0.5 as a percentage is 50%. You get this by multiplying 0.5 by 100, which gives 50, then adding the percent sign. This is the same as saying 0.5 is half, and half of 100% is 50%.

How do I convert a decimal to a percent without a calculator?

Move the decimal point two places to the right and add a percent sign. For example, 0.125 becomes 12.5% (the decimal point moves from between the 0 and 1 to between the 12 and 5). This shortcut works because multiplying by 100 is the same as shifting the decimal point two places right.

Decimeter to Meter Converter

How many meters is 1 decimeter?

1 decimeter equals 0.1 metres. The prefix 'deci' means one tenth, so a decimeter is exactly one tenth of a metre. To convert decimeters to metres, divide the number of decimeters by 10. For example, 25 decimeters equals 2.5 metres.

How do you convert meters to decimeters?

To convert metres to decimeters, multiply the number of metres by 10. For example, 3 metres equals 30 decimeters. This is the reverse of the decimeter to metre conversion, since there are 10 decimeters in every metre.

Where is the decimeter used in New Zealand?

New Zealand uses the metric system, but the decimeter is rarely used in everyday measurement. Most NZ measurements are expressed in millimetres, centimetres, metres, or kilometres. The decimeter appears mainly in scientific, engineering, and educational contexts where a unit between the centimetre and metre is useful, such as some European product packaging or scientific reference tables.

Degrees Minutes Seconds to Decimal Degrees Converter

How do you convert degrees, minutes and seconds to decimal degrees?

Decimal degrees equal degrees plus minutes divided by 60, plus seconds divided by 3600. For example, 41 degrees, 17 minutes, 11.4 seconds converts to 41 + (17/60) + (11.4/3600) = 41.2865 decimal degrees. If the coordinate is in the southern or western hemisphere (S or W), the result is expressed as a negative number.

Why are New Zealand coordinates negative in decimal degrees?

New Zealand sits in the southern hemisphere, so latitudes convert to negative decimal degrees, for example -41.2865 for Wellington. Longitude stays positive because New Zealand is east of the prime meridian, typically between 166 and 179 degrees. Mapping tools like Google Maps and GPS devices use this signed decimal format by default.

How accurate is a decimal degree conversion?

Each decimal place in a decimal degree represents roughly 11.1 km at the equator for the first decimal place, dropping to about 1.11 cm by the seventh decimal place. Four decimal places (about 11 metres of precision) is normally accurate enough for maps and navigation, while six or more decimal places is used for surveying and precise GPS work.

Degrees to Minutes Converter

How many minutes are in a degree?

There are 60 minutes of arc (arcminutes) in one degree, and 60 seconds of arc (arcseconds) in one minute. This is the same base-60 (sexagesimal) system used for hours, minutes and seconds in time. So 1 degree = 60 arcminutes = 3,600 arcseconds. To convert decimal degrees to minutes, multiply the decimal part by 60. For example, 12.5 degrees is 12 degrees and 0.5 x 60 = 30 minutes, written as 12° 30'.

How do I convert decimal degrees to degrees and minutes?

Take the whole number part as the degrees. Multiply the remaining decimal fraction by 60 to get the minutes. For example, for 47.835 degrees: the whole number is 47 degrees. The fraction 0.835 x 60 = 50.1 minutes. So 47.835 degrees equals 47° 50.1', or approximately 47° 50' 06" if you also convert the leftover 0.1 minutes to seconds (0.1 x 60 = 6 seconds).

Where are arcminutes used in New Zealand?

Arcminutes and arcseconds are used in New Zealand for GPS coordinates and land survey work, where latitude and longitude are sometimes expressed in degrees, minutes and seconds (DMS) rather than decimal degrees. LINZ (Land Information New Zealand) survey plans, marine navigation charts, and older topographic maps commonly use DMS notation. One minute of latitude is approximately 1.852 km (a nautical mile), which is why the format remains common in navigation and surveying.

Degrees to Seconds Converter

How many arcseconds are in a degree?

There are 3,600 arcseconds in one degree. This comes from a degree being divided into 60 arcminutes, and each arcminute being divided into 60 arcseconds (60 x 60 = 3,600). Arcseconds are used in astronomy, surveying, GPS coordinates and navigation wherever very precise angular measurement is needed, such as stating a star's position or a survey bearing.

What is the difference between arcseconds and seconds of time?

Arcseconds measure angle (1 degree = 3,600 arcseconds), while seconds of time measure how long it takes Earth to rotate through that angle. Because Earth rotates 360 degrees in 24 hours, 1 degree of rotation equals 240 seconds of time (24 hours x 3,600 seconds / 360 degrees). Seconds of time are used in astronomy and longitude calculations to relate angular position to the time of day.

How do I convert degrees, minutes and seconds to just seconds?

First convert the whole angle to decimal degrees: decimal degrees = degrees + minutes/60 + seconds/3600. Then multiply the decimal degrees by 3,600 to get the total in arcseconds. For example, 10 degrees 30 minutes 15 seconds equals 10.5042 decimal degrees, which equals 37,815 arcseconds.

Delta to Wye Conversion Calculator

What is the delta to wye conversion formula?

For a delta network with resistors Rab, Rbc and Rca, the equivalent wye resistances are: Ra = (Rab x Rca) / (Rab + Rbc + Rca), Rb = (Rab x Rbc) / (Rab + Rbc + Rca), and Rc = (Rbc x Rca) / (Rab + Rbc + Rca). Each wye resistor equals the product of the two adjacent delta resistors divided by the sum of all three delta resistors. If all three delta resistors are equal to R, each wye resistor equals R divided by 3.

How do you convert wye back to delta?

The reverse transform uses: Rab = (Ra Rb + Rb Rc + Rc Ra) / Rc, Rbc = (Ra Rb + Rb Rc + Rc Ra) / Ra, and Rca = (Ra Rb + Rb Rc + Rc Ra) / Rb. You calculate the sum of the three pairwise products of the wye resistors, then divide that sum by the wye resistor that is 'opposite' the delta resistor you are solving for. If all three wye resistors are equal to R, each delta resistor equals 3R.

Why convert between delta and wye configurations?

Delta (Δ) and wye (Y, also called star) are two ways of connecting three resistors, transformers, or three-phase loads between three terminals. Some circuits are difficult to simplify with standard series-parallel rules because the resistors are neither purely in series nor purely in parallel, such as bridge networks. Converting a delta section to its wye equivalent (or vice versa) lets you combine the transformed resistor with the rest of the circuit using ordinary series and parallel rules. It is also used in three-phase power systems to convert between delta-connected and star-connected loads or transformer windings.

Density Conversion Calculator

What is the formula for converting density units?

Every density unit can be converted through a common base unit, usually kilograms per cubic metre (kg/m3). Multiply your value by its conversion factor to kg/m3, then divide that result by the conversion factor of the unit you want. For example, to convert 1 g/cm3 to lb/ft3, first multiply by 1000 to get 1000 kg/m3, then divide by 16.01846 (the kg/m3 value of 1 lb/ft3) to get 62.4280 lb/ft3.

How do I convert g/cm3 to kg/m3?

Multiply the value in g/cm3 by 1000 to get kg/m3, because 1 gram per cubic centimetre equals 1000 kilograms per cubic metre. Water has a density of 1 g/cm3, which equals 1000 kg/m3. This is the most common density conversion used in engineering, chemistry, and materials science.

Why do g/cm3 and kg/L give the same number?

Because 1 cubic centimetre is exactly equal to 1 millilitre, and 1000 millilitres make up 1 litre. So a density expressed in grams per cubic centimetre is numerically identical to the same density expressed in kilograms per litre. Water at 1 g/cm3 is therefore also exactly 1 kg/L.

Density Converter

How do you convert g/cm3 to kg/m3?

Multiply g/cm3 by 1000 to get kg/m3. This is because 1 g/cm3 = 1000 kg/m3. For example, the density of water is 1 g/cm3, which equals 1000 kg/m3. This is the most common density conversion in engineering and materials science.

How many lb/ft3 is 1 g/cm3?

One gram per cubic centimetre equals 62.428 pounds per cubic foot. Water has a density of 1 g/cm3, so water weighs about 62.43 lb per cubic foot. To convert lb/ft3 to kg/m3, multiply by 16.0185.

What is the density of water in common units?

Water at 4 degrees Celsius has a density of exactly 1 g/cm3 = 1000 kg/m3 = 1 kg/L = 62.43 lb/ft3 = 8.345 lb per US gallon. These reference values are useful for checking conversions and for calculating the mass of known water volumes.

DNA to mRNA Converter

How do you convert DNA to mRNA?

During transcription, RNA polymerase reads the DNA template strand and builds a complementary mRNA strand. The mRNA sequence matches the DNA coding (sense) strand exactly, except that every thymine (T) is replaced with uracil (U). If you start from the template (antisense) strand instead, you first find the complementary base for each letter (A to U, T to A, C to G, G to C) to build the mRNA, since RNA polymerase reads the template 3' to 5' and synthesises mRNA 5' to 3'.

What is the difference between the coding strand and the template strand?

The coding strand (also called the sense strand) has the same sequence as the mRNA, with T instead of U. The template strand (antisense strand) is the strand that RNA polymerase actually reads, and it is complementary to both the coding strand and the mRNA. If you know the coding strand, converting to mRNA is a simple T-to-U swap. If you only have the template strand, you need to take its complement first.

Why does RNA use uracil instead of thymine?

Uracil and thymine are both pyrimidine bases that pair with adenine, but uracil lacks the methyl group found in thymine. Thymine's methyl group helps DNA repair enzymes distinguish original strands from mutated ones (deaminated cytosine looks like uracil, so using thymine in DNA lets repair machinery recognise stray uracil as damage). RNA is shorter-lived and does not need this repair distinction, and uracil is cheaper for the cell to produce, so RNA uses uracil in place of thymine.

Drops to mL Conversion Calculator NZ

How many drops are in 1 mL?

It depends on the dropper or drip set. The most common standard used for liquid medicine and eye drops is 20 drops per millilitre. Standard IV administration sets are labelled with their own drop factor, typically 10, 15, 20, or 60 drops per mL (macrodrip sets are 10 to 20 gtt/mL, microdrip or paediatric sets are 60 gtt/mL). Always check the packaging or giving set for the exact drop factor, since droplet size varies with liquid viscosity, surface tension, and the dropper tip opening.

Why do drop sizes vary between liquids?

Drop size depends on the liquid's viscosity and surface tension and on the diameter of the dropper tip or nozzle. Water-based liquids like eye drops or saline typically form drops close to 20 per mL with a standard dropper tip. Thicker or oilier liquids (such as some oral suspensions or essential oils) often form larger drops, meaning fewer drops make up a millilitre. This is why pharmacists and nurses use the specific drop factor printed on the medicine bottle or IV set rather than assuming 20 drops per mL for every liquid.

What is a drop factor in an IV drip?

A drop factor is the number of drops a specific IV giving set delivers per millilitre of fluid, printed on the packaging (for example 15 gtt/mL or 20 gtt/mL for macrodrip sets, and 60 gtt/mL for microdrip or paediatric sets). It is used with the prescribed flow rate to calculate the drip rate in drops per minute. This calculator converts between drops and millilitres using whatever drop factor you select, but it does not calculate infusion drip rates over time.

Duodecimal Converter

What is duodecimal?

Base 12, using digits 0 to 9 then A (ten) and B (eleven). It is also called the dozenal system.

Why would anyone use base 12?

Twelve divides evenly by 2, 3, 4 and 6, so common fractions come out neatly, which appeals to dozenal enthusiasts.

What is 100 in base 12?

84, because 100 is 8 twelves plus 4.

Energy Converter

How many joules are in a kilowatt-hour?

One kilowatt-hour equals exactly 3,600,000 joules (3,600 kilojoules or 3.6 megajoules). This is because one watt equals one joule per second, so one kilowatt running for one hour (3,600 seconds) produces 3,600,000 joules.

What is the difference between a calorie and a kilocalorie?

One kilocalorie (kcal) equals 1,000 small calories (cal). Food energy is measured in kilocalories, though they are often called Calories with a capital C on nutrition labels. One kcal equals 4,184 joules, while one small cal equals 4.184 joules.

What is a BTU?

A British Thermal Unit (BTU) is the amount of energy needed to raise one pound of water by one degree Fahrenheit. One BTU equals 1,055.06 joules. It is widely used in the US for heating and cooling equipment ratings.

Fahrenheit to Celsius Converter

What is the formula to convert Fahrenheit to Celsius?

The formula is C = (F − 32) × 5/9. Subtract 32 from the Fahrenheit temperature, then multiply the result by 5 and divide by 9. For example, 72°F gives (72 − 32) × 5/9 = 40 × 0.5556 = 22.22°C. The reverse formula (Celsius to Fahrenheit) is F = (C × 9/5) + 32.

What is 98.6°F in Celsius?

98.6°F equals exactly 37°C. This is normal human body temperature. The value 98.6°F was historically defined as the Fahrenheit equivalent of 37°C, so the conversion is exact: (98.6 − 32) × 5/9 = 66.6 × 5/9 = 37.0°C.

What temperature is the same in both Fahrenheit and Celsius?

The two scales are equal at −40 degrees. Both −40°F and −40°C are the same temperature. You can verify this with the formula: (−40 − 32) × 5/9 = −72 × 5/9 = −40°C. This is sometimes called the 'crossing point' of the two scales.

Feed Conversion Ratio Calculator NZ

How do you calculate feed conversion ratio?

Divide the feed eaten by the liveweight gained over the same period. On pasture systems both sides are usually in kilograms, with feed measured as dry matter rather than as fed, so the answer is kilograms of dry matter per kilogram of gain. A lower number means the feed is being converted more efficiently. Feed and gain must cover exactly the same animals over exactly the same days or the ratio means nothing.

Why is feed measured as dry matter?

Because feeds carry wildly different amounts of water, and comparing them as fed compares moisture as much as feed. Baleage might be 45 percent dry matter and hay 85 percent, so a tonne of each delivers quite different amounts of actual feed. Converting everything to a dry matter basis is what makes a ratio calculated on one feed comparable with one calculated on another.

What is a good feed conversion ratio?

It depends entirely on the species, the class of stock, the feed and how much of the intake is going to maintenance rather than gain, so no single benchmark is offered here. A useful comparison is against your own figure from a previous mob on similar feed, because that holds most of the variables still. The cost of gain per kilogram is often the more decisive number anyway, since a poorer ratio on cheap feed can beat a better one on expensive feed.

File Size Converter

What is the difference between MB and MiB?

MB (megabyte) uses the decimal SI standard where 1 MB equals 1,000,000 bytes (10 to the power of 6). MiB (mebibyte) uses the binary IEC standard where 1 MiB equals 1,048,576 bytes (2 to the power of 20). Hard drive manufacturers use decimal MB, which is why a 1 TB drive shows up as about 931 GiB in Windows.

How many bytes are in 1 GB?

In the decimal SI system, 1 GB equals exactly 1,000,000,000 bytes. In the binary IEC system, 1 GiB (gibibyte) equals 1,073,741,824 bytes. Most operating systems historically used binary counts but labelled them as GB, which caused confusion with storage capacity.

How do I convert megabytes to megabits?

Multiply megabytes by 8 to get megabits, since there are 8 bits in every byte. A 1.5 MB file is 12 megabits. Internet speeds are measured in megabits per second (Mbps), so this conversion is important when calculating download times.

Foot to Centimeter Converter

How many centimetres is one foot?

One foot is exactly 30.48 centimetres. This is an exact definition under the international yard and pound agreement of 1959, which defined 1 inch as exactly 2.54 cm. Since there are 12 inches in a foot, 1 foot equals 12 x 2.54 = 30.48 cm exactly.

How do I convert 5 feet 10 inches to centimetres?

Convert the feet and inches to a total number of inches first, then multiply by 2.54. 5 feet 10 inches equals (5 x 12) + 10 = 70 inches. 70 x 2.54 = 177.8 cm. Alternatively, convert the feet and inches separately and add: 5 x 30.48 = 152.4 cm plus 10 x 2.54 = 25.4 cm gives 177.8 cm.

Why do New Zealanders use both feet and centimetres?

New Zealand officially adopted the metric system in the early 1970s, so centimetres are the standard unit for height and length in official, medical, and scientific contexts. However, feet and inches remain widely used informally, especially for personal height, because many older New Zealanders grew up with imperial measurements and the usage has persisted across generations. It is common for people to know their height in both feet-and-inches and centimetres.

Force Converter

How do you convert newtons to pounds-force?

One newton equals 0.22481 pounds-force (lbf). To convert newtons to lbf, multiply by 0.22481. To convert lbf to newtons, multiply by 4.44822. For example, 1 kN (1000 N) equals 224.81 lbf.

What is a kilogram-force?

A kilogram-force (kgf) is the force exerted by a one-kilogram mass under standard gravity (9.80665 m/s squared). One kgf equals exactly 9.80665 newtons. It is a legacy unit still used in some engineering contexts, particularly for hydraulic pressure rated in kgf per square centimetre.

What is a kip?

A kip is a unit of force equal to 1000 pounds-force (1 kilopound-force). It is used primarily in US structural engineering to express large forces and loads. One kip equals approximately 4448.22 newtons or 4.448 kN.

Free to Paid Conversion Calculator

What is a typical free to paid conversion rate?

Freemium conversion rates are usually low, often in the low single digits, because most free users never intend to pay. A rate of a few percent can be perfectly healthy at scale. Compare against your own trend rather than chasing a headline benchmark.

Should I measure all free users or active ones?

Either can work, but you must be consistent. Measuring against all free users ever gives a lower rate than measuring active free users in a window. Pick the definition that matches how you think about your base and apply it every period.

How do I lift the conversion rate?

Make the value of paying clear at the moment users feel a limit, such as hitting a usage cap or needing a team feature. Tuning where the free tier ends and prompting at the right time both help. Segmenting by cohort shows which users are most likely to upgrade.

Feet to Metres Converter

How many metres are in a foot?

One foot equals exactly 0.3048 metres. To convert feet to metres, multiply the number of feet by 0.3048. For example, 6 feet is 6 times 0.3048, which is 1.829 metres.

How do I convert metres to feet?

Divide the number of metres by 0.3048, or multiply by about 3.281. For example, 2 metres is 2 divided by 0.3048, which is about 6.56 feet.

Why does New Zealand use metres?

New Zealand uses the metric system, so distances, heights, and building dimensions are in metres and millimetres. Feet still appear in some contexts like aviation, diving, and imported products, which is when a quick conversion is useful.

Grams to Pounds Converter (g to lbs)

How many pounds is 100 grams?

100 grams is equal to 0.2205 pounds (lbs), or approximately 3.527 ounces. The exact conversion is 100 / 453.59237 = 0.220462 lbs. This is a common weight for small food items, spice packets, and ingredients.

What is the exact formula to convert grams to pounds?

The exact formula is: pounds = grams / 453.59237. This is the internationally agreed value defined in 1959 by the International Yard and Pound Agreement. Since 1 pound equals exactly 453.59237 grams, dividing the gram value by 453.59237 gives pounds. To also get ounces, take the decimal part of the pounds result and multiply by 16.

How do I convert grams to pounds and ounces?

First divide grams by 453.59237 to get total pounds as a decimal. The whole-number part is the pounds. Multiply the remaining decimal by 16 to get ounces. For example, 500 g / 453.59237 = 1.1023 lbs. The whole-number part is 1 lb. The decimal 0.1023 x 16 = 1.637 oz. So 500 g = 1 lb 1.64 oz.

Grams to Cups Converter

How many grams are in a cup in New Zealand?

A New Zealand metric cup holds 250 mL of liquid. For water or milk (density approximately 1 g/mL), 1 cup equals roughly 250 g. For ingredients with a different density the weight per cup changes significantly. For example, 1 cup of plain flour (sifted and lightly spooned) weighs about 125 g, while 1 cup of white sugar weighs about 220 g. Always check the density of your specific ingredient, since a cup of flour and a cup of sugar differ by nearly 100 g.

What is the difference between a NZ metric cup and a US cup?

A New Zealand (and Australian) metric cup is 250 mL. A US customary cup is approximately 236.6 mL, often rounded to 240 mL for practical purposes. The difference is about 4 to 6 percent. For most home baking recipes the difference is small enough to ignore, but for large quantities or recipes requiring precision it is worth selecting the correct cup size. This converter lets you choose between NZ metric (250 mL) and US cups (240 mL).

Why does the grams-per-cup value differ between ingredients?

The number of grams in a cup depends entirely on the density of the ingredient. Dense liquids such as honey (about 340 g per metric cup) weigh much more than airy dry ingredients such as rolled oats (about 90 g per metric cup) or cocoa powder (about 100 g per metric cup). Flour values also vary by type: plain flour is typically 125 g per metric cup, while bread flour can be slightly heavier. For the most accurate baking results, weigh ingredients in grams using kitchen scales rather than relying on cup measurements.

Grams to Ounces Calculator

How many ounces is 100 grams?

100 grams equals 3.5274 ounces (avoirdupois). The exact conversion factor is 1 oz = 28.349523125 g, so 100 g divided by 28.349523125 gives 3.52739619... oz, which rounds to 3.527 oz to three decimal places.

What is the difference between avoirdupois ounces and troy ounces?

Avoirdupois ounces (oz av) are the standard ounce used for everyday goods, food, and postage. One avoirdupois ounce equals 28.349523125 grams. Troy ounces (oz t) are used for precious metals such as gold and silver. One troy ounce equals 31.1034768 grams, making it about 10% heavier than an avoirdupois ounce. This calculator uses avoirdupois ounces unless you select the troy option.

How do I convert ounces back to grams?

To convert ounces to grams, multiply the number of ounces by 28.349523125. For example, 5 oz x 28.349523125 = 141.748 g. This calculator includes a reverse field so you can enter ounces and read the grams result directly.

Hexadecimal Converter

What is hexadecimal?

Base sixteen, using digits 0 to 9 and letters A to F. It is a compact way to write binary, with one hex digit per four bits.

What is 255 in hex?

FF, the largest value of a single byte.

Why do programmers use hex?

How do I remove HTML tags from text?

Paste the HTML here and the converter strips all the tags, decodes entities and tidies the whitespace, leaving just the readable text. It runs in your browser, so you get clean plain text instantly without any markup.

Does it decode HTML entities?

Yes. Codes such as those for the ampersand, angle brackets and non-breaking spaces are converted back into the characters they represent, using the browser's own parser. So an ampersand entity becomes a real ampersand in the output.

What happens to links and formatting?

They are discarded. This tool extracts plain text only, so links become their visible text, and formatting like bold, headings and lists becomes ordinary lines. That is the intended behaviour when you want clean text without any markup.

No. The conversion runs entirely in your browser using JavaScript. Nothing you paste is sent to a server, so your data stays private on your own device.

What JSON format does it expect?

It expects a JSON array of objects, starting with a square bracket, where each object has named fields. The tool collects the keys across all objects to build the header row. A single object on its own should be wrapped in an array first.

How are commas and quotes inside values handled?

Any value that contains a comma, a double quote or a line break is wrapped in double quotes, and internal quotes are doubled. This is the standard CSV escaping that Excel and Google Sheets read correctly, so your columns stay aligned.

JSON to Query String Converter NZ

What is a query string?

It is the part of a URL after the question mark: a set of key-value pairs joined by ampersands, such as name=Calculate&page=2. It carries parameters that drive searches, filters and other behaviour. Values are percent-encoded so special characters stay valid in the URL.

How do I build a query string from JSON?

Each property of the object becomes a key-value pair, with the key and value URL-encoded and the pairs joined by ampersands. This tool does it for you, encoding spaces and special characters so the resulting query string is valid in a URL.

Does it handle nested objects and arrays?

It works best with flat objects of simple values, which is what query strings naturally represent. Nested objects and arrays can be encoded in several competing conventions, so for those a library matching your web framework is the safer choice.

JSON to YAML Converter NZ

Why convert JSON to YAML?

YAML is easier for people to read and edit than JSON, using indentation instead of braces, quotes and commas. It is the standard for configuration files in tools like Docker, Kubernetes and CI pipelines, so converting JSON data into YAML is common when preparing configs.

Does the conversion change the data?

No. JSON and YAML represent the same structure, so the conversion preserves every object, list and value exactly. It only changes the presentation, from JSON's punctuation-heavy style to YAML's lighter, indentation-based style. The data is identical.

What if my JSON is invalid?

The converter validates the JSON first and tells you if it is not valid, so you can fix the error, such as a trailing comma or a missing quote, before converting. Valid JSON is required because YAML is built from the parsed structure.

mL to Grams Calculator

How do you convert mL to grams?

To convert millilitres to grams, multiply the volume in mL by the density of the substance in g/mL. The formula is: mass (g) = volume (mL) x density (g/mL). For water, the density is 1 g/mL, so 1 mL equals 1 gram. For other substances the density differs: flour is about 0.53 g/mL, so 100 mL of flour weighs approximately 53 g. Always check the density for the specific substance you are measuring.

Is 1 mL equal to 1 gram?

1 mL equals 1 gram only for water at approximately 4 degrees Celsius (its maximum density). For other substances, the conversion depends on density. Milk is close to water at about 1.03 g/mL, so 1 mL of milk weighs around 1.03 g. Cooking oil is lighter than water at about 0.92 g/mL, meaning 1 mL of oil weighs only 0.92 g. Flour is much lighter at about 0.53 g/mL, so 1 mL of flour weighs around 0.53 g. Honey is heavier at about 1.42 g/mL.

Why do recipes sometimes list ingredients in mL and sometimes in grams?

Liquid ingredients like water, milk, and oil are often given in millilitres because they are easy to measure in a jug or measuring cup. Dry ingredients like flour, sugar, and cocoa are more accurately measured by weight in grams because the volume of a dry ingredient varies depending on how tightly it is packed. A lightly scooped cup of flour and a firmly packed cup can differ in mass by 20 to 30 percent. Weighing in grams produces more consistent and accurate baking results.

MM to M Conversion

How many millimetres are in a metre?

There are exactly 1,000 millimetres in one metre. The prefix 'milli' means one-thousandth, so a millimetre is one-thousandth of a metre (0.001 m). To convert millimetres to metres, divide by 1,000. For example, 500 mm equals 0.5 m, and 2,500 mm equals 2.5 m.

How do I convert mm to m without a calculator?

To convert millimetres to metres by hand, simply move the decimal point three places to the left (or divide by 1,000). For example: 150 mm becomes 0.150 m; 3,200 mm becomes 3.200 m; 75 mm becomes 0.075 m. Since 1 m = 1,000 mm, dividing by 1,000 is all that is needed.

What is 1 mm in metres?

1 millimetre equals 0.001 metres (one-thousandth of a metre). It also equals 0.1 centimetres and 0.000001 kilometres. Millimetres are commonly used in engineering, construction, and manufacturing where fine precision is needed.

Nm to ft-lbs Converter

How many ft-lbs is 1 Nm?

1 newton metre (Nm) is equal to approximately 0.737562 foot-pounds (ft-lb). This comes from the definition of each unit: 1 Nm = 1 newton x 1 metre, and 1 ft-lb = 1 pound-force x 1 foot. Since 1 pound-force = 4.44822 N and 1 foot = 0.3048 m, one ft-lb = 4.44822 x 0.3048 = 1.35582 Nm. The reciprocal gives 1 Nm = 1/1.35582 = 0.737562 ft-lb.

Why do torque specs sometimes use Nm and sometimes ft-lbs?

Newton metres (Nm) are the SI (metric) unit of torque used in most countries and by most vehicle manufacturers outside North America. Foot-pounds (ft-lb) are the imperial unit still widely used in the United States and in American-brand vehicle service manuals. When working on vehicles or machinery, the torque wrench and the service manual must match. If your wrench reads in ft-lb but the spec is in Nm, use this converter to avoid over or under-tightening fasteners.

Is ft-lb the same as lb-ft?

Yes, ft-lb and lb-ft are the same unit of torque and the two abbreviations are used interchangeably in practice. Strictly, the preferred engineering notation is lbf-ft (pound-force foot) to distinguish it from the unit of energy (foot-pound-force used in work/energy contexts), but in everyday use ft-lb and lb-ft both mean the same thing when referring to torque. This converter uses ft-lb throughout.

Numeral System Converter

Why do computers use binary?

Computers use binary (base 2) because electronic circuits naturally represent two states: on (1) and off (0). Every piece of data a computer processes is ultimately stored and manipulated as combinations of these two states. Binary maps directly to transistor logic, making it the most practical number system for digital hardware.

How do you convert decimal to hexadecimal?

To convert decimal to hexadecimal, divide the decimal number by 16 repeatedly, recording the remainder at each step using 0-9 for remainders 0-9 and A-F for remainders 10-15. The hex number is the remainders read from bottom to top. For example, 255 divided by 16 gives 15 remainder 15, which is FF in hex.

What is octal used for?

Octal (base 8) was widely used in early computing because three binary digits map exactly to one octal digit, making it a compact shorthand for binary. Today octal is primarily used in Unix and Linux file permission codes (for example chmod 755) where each octal digit represents three permission bits (read, write, execute).

Octal Converter

What is octal?

Base eight, using digits 0 to 7. Each octal digit equals three binary bits.

Where is octal used today?

Most visibly in Unix and Linux file permissions, such as chmod 755.

What is 64 in octal?

100, because 64 is 8 squared.

Odds to Probability Converter NZ

How do I convert probability to odds?

Odds against an event are the probability it does not happen divided by the probability it does, written as a ratio. So a 25 percent chance gives odds of 0.75 to 0.25, or 3 to 1 against. Decimal odds are simply one divided by the probability.

What are decimal odds?

Decimal odds, standard in sports betting, show the total return per dollar staked, including your stake. They equal one divided by the probability, so a 25 percent chance is decimal odds of 4.0: a winning dollar returns four. Lower odds than this fair value reflect the bookmaker's margin.

What is implied probability?

Implied probability is the chance suggested by a set of odds, found by reversing the conversion. From decimal odds it is one divided by the odds. Comparing implied probability with your own estimate is how bettors judge whether odds offer value.

Ounce to Kg Converter

How many kilograms is 1 ounce?

One ounce (avoirdupois) equals exactly 0.0283495231 kilograms, or approximately 28.35 grams. This is the standard international conversion factor defined under the International Yard and Pound Agreement of 1959. To convert any weight in ounces to kilograms, multiply the number of ounces by 0.0283495231.

How do I convert ounces to kilograms?

To convert ounces to kilograms, multiply the number of ounces by 0.0283495231. For example, 16 oz x 0.0283495231 = 0.4536 kg (one pound). A quick mental approximation is to divide the ounces by 35.274, which is the number of ounces in one kilogram.

What is the difference between a troy ounce and an avoirdupois ounce?

The avoirdupois ounce (used for everyday weights, food, and body weight) equals 28.3495 grams. The troy ounce (used for precious metals like gold and silver) equals 31.1035 grams. This converter uses the avoirdupois ounce. If you are converting gold or silver weights, use a troy ounce converter, as 1 troy oz = 0.0311035 kg, not 0.0283495 kg.

Ounces to Millilitres Converter

How many millilitres are in a fluid ounce?

One US fluid ounce equals exactly 29.5735295625 millilitres. One Imperial (UK) fluid ounce equals exactly 28.4130625 millilitres. The US fluid ounce is more commonly used in recipes and product labels internationally, so unless a recipe specifies Imperial, assume US fluid ounces.

How do I convert ounces to millilitres?

Multiply the number of fluid ounces by 29.5735 (for US fl oz) or by 28.4131 (for Imperial fl oz). For example, 8 US fl oz multiplied by 29.5735 equals 236.59 mL, which is a standard US cup. For a quick mental estimate, multiply by 30: 8 fl oz is approximately 240 mL.

Is an ounce of liquid the same as an ounce of weight?

No. A fluid ounce (fl oz) is a unit of volume, not weight. A weight ounce (oz) measures mass. One weight ounce equals 28.3495 grams. One US fluid ounce equals 29.5735 mL. For water specifically, 1 US fl oz of water weighs approximately 29.57 grams, because water has a density close to 1 g/mL. For other liquids such as oil or honey, the weight per fluid ounce will differ.

Pounds to Grams Converter

How many grams are in a pound?

There are exactly 453.59237 grams in one pound (lb). This is the internationally agreed conversion factor under the International Yard and Pound Agreement of 1959. For most everyday purposes, rounding to 453.59 g or even 454 g is accurate enough.

How do I convert pounds to grams without a calculator?

Multiply the number of pounds by 454 for a quick approximation. For example, 2 lb is roughly 2 x 454 = 908 g. For a more precise result, multiply by 453.59. So 2 lb = 2 x 453.59 = 907.18 g. Using 454 is accurate to within 0.09 percent, which is fine for cooking and general use.

Is a pound the same in all countries?

The pound referred to in everyday use today is the avoirdupois pound, defined as exactly 453.59237 grams. This is the standard pound used in the United States, the United Kingdom, and throughout most of the world for general weighing. There are historical variants such as the troy pound (373.24 g, used for precious metals) and the apothecaries' pound, but when people say 'pound' for food, body weight, or general goods, they mean the avoirdupois pound.

Power Converter

How many watts are in one horsepower?

One mechanical horsepower equals exactly 745.69987 watts, commonly rounded to 745.7 W. This is the standard definition of horsepower used for engine and motor ratings in most countries. Electric horsepower is slightly different at 746 W exactly.

What is BTU per hour?

BTU per hour (BTU/hr) is a unit of power measuring how many British Thermal Units of energy are transferred per hour. It is widely used in the United States for heating and cooling system ratings. One BTU/hr equals 0.29307 watts, so a 10,000 BTU/hr air conditioner is roughly 2,931 watts.

How do I convert kilowatts to horsepower?

RGB to HSL Converter

What is the difference between RGB and HSL?

RGB sets a colour by mixing red, green and blue light, each from 0 to 255. HSL sets the same colour by its hue angle, its saturation and its lightness. They describe identical colours, but HSL is usually easier to tweak by hand.

What range do the values use?

Red, green and blue each run from 0 to 255. Hue is an angle from 0 to 360 degrees, while saturation and lightness are percentages from 0 to 100. The hex code is the same colour written as six hexadecimal digits.

Is HSL lightness the same as brightness?

Not quite. HSL lightness is a mathematical midpoint between the lightest and darkest channels, not how bright the colour looks to your eye. Two colours with the same lightness can appear to differ in weight, so trust your eye for final tuning.

Ring Size Converter

How do I measure my ring size?

Measure the inside diameter of a ring that fits, across the middle in millimetres, or wrap a strip of paper around your finger and measure the circumference. Enter either here and the converter finds your size. Measure when your hands are warm, not cold.

What ring size system does New Zealand use?

New Zealand uses the same alphabetical sizing as the UK and Australia, where sizes are letters from about F up to Z. The US uses numbers instead, roughly 3 to 13. This converter shows the NZ/UK/AU letter and the US number side by side.

How does diameter relate to ring size?

Ring size is set by the inside diameter or circumference of the band. A larger diameter means a larger size. For example, an inside diameter of about 17.3 mm is a US size 7, or an NZ/UK/AU size N and a half.

Roman Numeral Converter

How do Roman numerals work?

Roman numerals use letters: I is 1, V is 5, X is 10, L is 50, C is 100, D is 500, and M is 1000. Letters are added together, but a smaller letter before a larger one is subtracted, so IV is 4 and IX is 9.

What is the largest Roman numeral?

Using the standard letters, the largest commonly written value is 3,999, or MMMCMXCIX. Beyond that, bars over letters were used to multiply by a thousand. This converter handles 1 to 3,999.

Is there a zero in Roman numerals?

No. The Roman system has no symbol for zero, which is one reason it is awkward for arithmetic. It starts at one, written I.

Scientific Notation Converter

How do you convert scientific notation to standard form?

Scientific notation writes a number as a coefficient times 10 raised to an exponent: for example, 4.5 times 10 to the power of minus 5 (written 4.5e-5). To convert to decimal, move the decimal point in the coefficient by the number of places indicated by the exponent. A negative exponent moves it left: 4.5e-5 becomes 0.000045. A positive exponent moves it right: 1.23e8 becomes 123,000,000.

When is scientific notation used?

Scientific notation is used whenever numbers are very large or very small, making them impractical to write in full. In chemistry you encounter Avogadro's number (6.022e23), in physics the charge of an electron (1.602e-19 coulombs), and in engineering you might see material properties like Young's modulus (2e11 Pa) or the permeability of free space (1.257e-6 H/m). It also prevents ambiguity about the number of significant figures.

What is the difference between e notation and times-10 notation?

They are the same number, just written differently. 4.5e-5 is the computer or calculator notation for 4.5 times 10 to the power of negative 5. The 'e' stands for exponent. Written in traditional mathematical notation it would be 4.5 times 10 superscript minus 5. Most calculators, programming languages, and spreadsheets accept the e notation directly.

Scientific to Decimal Notation Converter

What is scientific notation?

Scientific notation is a way of writing very large or very small numbers in a compact form: a x 10^n, where the coefficient a is a number with one non-zero digit before the decimal point (so 1 is less than or equal to |a| which is less than 10), and n is an integer exponent. For example, 35,000 is written as 3.5 x 10^4, and 0.0062 is written as 6.2 x 10^-3. Scientific notation is widely used in science, engineering, and computing to avoid writing long strings of zeros.

How do you convert scientific notation to decimal?

To convert scientific notation (a x 10^n) to decimal: if n is positive, move the decimal point in a to the right by n places, adding zeros as needed. If n is negative, move the decimal point to the left by |n| places, adding a leading zero as needed. For example, 2.5 x 10^4 means move the decimal point 4 places right: 2.5 becomes 25,000. And 2.5 x 10^-4 means move the decimal point 4 places left: 2.5 becomes 0.00025.

How do you convert a decimal number to scientific notation?

To convert a decimal to scientific notation: move the decimal point until you have exactly one non-zero digit to the left of it. Count the number of places you moved it. If you moved left, the exponent is positive; if you moved right, it is negative. For example, 48,000 becomes 4.8 x 10^4 (moved 4 places left), and 0.0031 becomes 3.1 x 10^-3 (moved 3 places right).

Shoe Size Conversion NZ

What shoe size system does New Zealand use?

New Zealand uses UK shoe sizing, the same as the United Kingdom and Australia. So if you know your NZ size, it is your UK size. This tool converts that to US and European sizes and to the foot length in centimetres.

How do I measure my foot length?

Stand on a piece of paper with your heel against a wall and mark the tip of your longest toe. Measure from the wall to the mark in centimetres, and measure both feet in the afternoon when they are largest. Use the larger foot and match the centimetre length in the chart.

Why do sizes differ between brands?

Conversion charts are a guide, but the fit varies by brand and style because each maker uses its own lasts. If you are between sizes or buying online, the centimetre length is the most reliable measure to compare against a brand's own size guide.

Square Metre Calculator

How do I calculate square metres?

Multiply length by width, with both in metres. A room 5 m long and 4 m wide is 5 x 4, which is 20 square metres. If you measured in centimetres, multiply the two numbers and divide by 10,000, because there are 10,000 square centimetres in a square metre.

How do I work out the area of several rooms?

Calculate the area of each room, then add them together. For identical areas, enter the size once and set the quantity. For different room sizes, total them up separately.

How much extra should I allow for flooring or paint?

For flooring and tiling, add about 5 to 10% for cuts and waste. For paint, divide the area by the coverage rate on the tin (often around 10 to 14 square metres per litre per coat) and remember you usually need two coats.

Stock Yard Sizing Calculator NZ

How big should a set of stock yards be?

Size them for the largest mob you will actually handle at once, not the average one, because the day the yards are too small is the day it matters. The total area is the mob size multiplied by the space each animal needs, which differs enormously between weaners and mature cattle and between cattle and sheep. Yards that are too small are dangerous and slow; yards that are far too large are hard to work stock in, so bigger is not automatically better.

How much space does an animal need in a yard?

It depends on the class and size of stock and on how long they will be held, so no single figure is supplied here. Holding pens where stock stand for a while need more room than a forcing pen where they are packed to move them forward. The right figures come from a yard designer or from the standards your council or processor expects, and the number you choose here should be one you can point at.

Why can yards be too large?

Because stock work best when they have somewhere obvious to go and a person can control the space. An oversized pen lets a mob spread out, mill and turn back, which takes longer and is more dangerous than a pen sized to fill properly. The forcing pen in particular relies on being tight enough to keep animals moving forward, which is why it is sized separately here rather than as a share of the total.

Stone to Kg Converter

How many kilograms are in a stone?

One stone is exactly 6.35029 kilograms. A stone is made up of 14 pounds, and each pound is about 0.4536 kilograms. So to convert stones to kilograms you multiply by 6.35029.

How do you convert stones and pounds to kilograms?

Multiply the stones by 14 to get the total pounds, add any extra pounds, then multiply by 0.453592 to get kilograms. For example, 11 stone is 154 pounds, which is about 69.85 kilograms.

Is stone still used in New Zealand?

New Zealand uses kilograms for body weight, but stones and pounds still appear in older records, in conversation, and in British and some other overseas contexts, so it is handy to be able to convert between them.

Temperature Conversion Calculator

How do you convert Celsius to Fahrenheit?

To convert Celsius to Fahrenheit, multiply by 9/5 and then add 32. The formula is: F = (C x 9/5) + 32. For example, 100 degrees Celsius equals (100 x 1.8) + 32 = 212 degrees Fahrenheit. A quick mental shortcut is to double the Celsius value and add 30, which gives a rough but useful approximation for everyday temperatures.

How do you convert Fahrenheit to Celsius?

To convert Fahrenheit to Celsius, subtract 32 and then multiply by 5/9. The formula is: C = (F - 32) x 5/9. For example, 98.6 degrees Fahrenheit equals (98.6 - 32) x 5/9 = 37 degrees Celsius. A quick mental check: 32 F is freezing (0 C), 68 F is a warm room (20 C), and 212 F is boiling (100 C).

What is absolute zero in Celsius and Fahrenheit?

Absolute zero is the lowest theoretically possible temperature, where particles have minimum thermal energy. It is defined as 0 Kelvin (K), which equals -273.15 degrees Celsius or -459.67 degrees Fahrenheit. At absolute zero, all classical molecular motion stops. This temperature has never been fully achieved in practice, though scientists have reached within billionths of a degree of it in laboratory conditions.

Temperature Converter

How do I convert Celsius to Fahrenheit?

Multiply the Celsius temperature by 9, divide by 5, and add 32. So 20 degrees Celsius is 20 times 9 divided by 5 plus 32, which is 68 degrees Fahrenheit. The converter does it both ways as you type.

What is Kelvin?

Kelvin is the scientific temperature scale that starts at absolute zero, the coldest possible temperature. To convert from Celsius, add 273.15. Water freezes at 273.15 Kelvin and boils at 373.15 Kelvin.

At what temperature do Celsius and Fahrenheit meet?

They are equal at minus 40 degrees. Minus 40 Celsius is the same as minus 40 Fahrenheit, the one point where the two scales cross.

Text Case Converter NZ

What is camelCase?

camelCase joins words together with no spaces, lower-casing the first word and capitalising the first letter of each word after it, such as firstName. It is the standard naming style for variables and functions in JavaScript, Java and many other programming languages.

What is the difference between Title Case and Sentence case?

Title Case capitalises the first letter of every word, as used in headings and titles. Sentence case capitalises only the first letter of each sentence, like ordinary writing. This tool produces both so you can pick the one your style guide requires.

When should I use snake_case or kebab-case?

snake_case, with underscores, is common in Python and for database column names. kebab-case, with hyphens, is the usual choice for web addresses, file names and CSS classes. Both keep everything lower case and avoid spaces, which suits code and URLs.

Torque Converter

How do you convert Newton-metres to foot-pounds?

One newton-metre equals 0.7376 foot-pounds. To convert N-m to ft-lb, multiply by 0.7376. To convert ft-lb to N-m, multiply by 1.35582. For example, 1 N-m equals 0.7376 ft-lb, and 100 ft-lb equals 135.58 N-m.

What is a kilogram-force metre?

A kilogram-force metre (kgf-m) is a legacy torque unit equal to the torque produced by a one-kilogram-force acting at a one-metre radius. Since one kgf equals 9.80665 N, one kgf-m equals 9.80665 N-m. It is still used in some older machine specifications and in some Asian countries.

How many inch-pounds in a foot-pound?

There are exactly 12 inch-pounds (in-lb or in-lbf) in one foot-pound (ft-lb or ft-lbf), because one foot equals 12 inches. Inch-pounds are commonly used for small fastener torque specifications, such as electronics or appliance screws, while foot-pounds are used for larger automotive and structural fasteners.

UK to US Shoe Size Converter

How do I convert UK shoe sizes to US sizes?

The conversion depends on gender. For men's shoes, US size = UK size + 0.5 (so UK 9 = US 9.5). For women's shoes, US size = UK size + 2 (so UK 6 = US 8). For children's shoes, US size = UK size + 0.5 (so UK 3 = US 3.5). These offsets reflect historical differences in how the UK and US developed their sizing systems, both of which are based on barleycorn increments (one third of an inch per size).

Is a UK size 8 the same as a US size 8?

No. A UK men's size 8 is equivalent to a US men's size 8.5. A UK women's size 8 is equivalent to a US women's size 10. Never assume UK and US sizes are identical, as this is one of the most common mistakes when ordering shoes online from overseas retailers.

What EU shoe size is a UK 7?

A UK size 7 corresponds to approximately EU size 40-41 for men and EU size 39-40 for women. EU sizes are based on Paris points (two thirds of a centimetre per size) and are unisex in the European system, though the starting point differs slightly between men's and women's lasts. The converter above shows the EU equivalent alongside the US size.

Unix Timestamp Converter

What is a Unix timestamp?

A Unix timestamp (also called epoch time or POSIX time) is the number of seconds that have elapsed since 1 January 1970 00:00:00 UTC, not counting leap seconds. It is the standard way that operating systems, databases and programming languages store and compare times, because it is a single integer that works consistently across time zones.

What Unix timestamp is 2024-06-24 12:00:00 UTC?

The Unix timestamp for 2024-06-24 12:00:00 UTC is 1719230400. You can verify this by entering that timestamp in the converter above and checking the UTC date shown. The converter also shows the equivalent local time in your browser's time zone.

What is the maximum Unix timestamp?

The maximum Unix timestamp for a 32-bit signed integer is 2147483647, which corresponds to 19 January 2038 03:14:07 UTC. This is the Year 2038 problem. Modern systems use 64-bit integers for timestamps, which supports dates billions of years into the future and removes any practical limit.

US to UK Shoe Size Converter

How do I convert US shoe sizes to UK sizes?

For men's shoes, subtract 0.5 from the US size to get the UK size (US 10 = UK 9.5). For women's shoes, subtract 2 from the US size to get the UK size (US 8 = UK 6). For children's shoes, subtract 0.5 from the US size to get the UK size (US 4 = UK 3.5). These conversions apply to standard adult and children's sizing used by most footwear brands.

Why are US and UK shoe sizes different?

US and UK shoe sizes both use systems based on barleycorn units (one-third of an inch), but the two systems start at different points. The UK system begins its scale at 0, while the US system is offset by half a size for men and two full sizes for women. This historical difference means a direct conversion is needed rather than a simple renaming of the same number.

Are US and UK women's shoe sizes the same as men's sizing systems?

No. Men's US and UK sizes differ by 0.5 (UK = US minus 0.5), but women's US and UK sizes differ by 2 full sizes (UK = US minus 2). This larger gap for women reflects historical sizing conventions in each country. A US women's 9 equals a UK women's 7, while a US men's 9 equals a UK men's 8.5.

Vigesimal Converter

What is vigesimal?

Base 20, using digits 0 to 9 then A to J for ten to nineteen.

Who used base 20?

The Maya civilisation used a vigesimal system, and traces survive in languages such as French and Danish.

What is 100 in base 20?

50, because 100 is exactly 5 twenties.

Voltage Converter

How many millivolts are in a volt?

Exactly 1,000. The prefix milli means one thousandth, so 1 mV is 0.001 V. This is an SI definition rather than a measured conversion, so no rounding error is introduced either way.

What voltage is mains power in New Zealand?

Nominally 230 volts single phase and 400 volts three phase at the point of supply. Distribution upstream of that runs at 11 kV and higher. Only a registered electrician should work on mains wiring.

Can voltage be negative?

Yes. Voltage is a potential difference between two points, so the sign depends on which point you treat as the reference. A reading of minus 2.5 V simply means the polarity is the other way round from your reference.

Are the volume conversion factors the same worldwide?

The metric factors are exact and universal: 1 litre is always 1,000 millilitres and 1,000 cubic centimetres. Be aware that gallons, pints, cups and fluid ounces have different US and imperial (UK) definitions, so check which system a unit follows before you rely on it. Every conversion runs instantly in your browser.

YAML to JSON Converter NZ

Why convert YAML to JSON?

YAML is easy for people to edit, so configuration is often written in it, but most programs and APIs consume JSON. Converting lets you take a human-edited YAML config and feed it to code that expects JSON, without rewriting the data by hand.

Does it handle nested data and lists?

Yes. It uses indentation to track nesting, so nested objects and lists convert correctly, and dashed lines become array items. It also recognises numbers, booleans and null so they become the right JSON types rather than quoted strings.

Are advanced YAML features supported?

Not fully. YAML has advanced features like anchors, references, multi-line block scalars and flow style that this converter does not support. It handles the everyday indentation-based maps, lists and scalars that make up most real configuration files.
