How do you convert centimetres to metres?

To convert centimetres to metres, divide the number of centimetres by 100. This is because there are exactly 100 centimetres in one metre. For example, 175 cm divided by 100 equals 1.75 m. The formula is: m = cm / 100.

How do you convert metres to centimetres?

To convert metres to centimetres, multiply the number of metres by 100. For example, 1.75 m multiplied by 100 equals 175 cm. The formula is: cm = m x 100.

What is 100 cm in metres?

100 cm equals exactly 1 metre. This is the defining relationship between the two units: one metre is subdivided into 100 centimetres. So 200 cm = 2 m, 50 cm = 0.5 m, and 1 cm = 0.01 m.

How to Convert Centimetres to Metres

The centimetre and the metre are both units of length in the International System of Units (SI). The relationship between them is exact: one metre equals exactly 100 centimetres. To convert centimetres to metres, divide by 100. To convert metres to centimetres, multiply by 100.

The formula is:

Metres = Centimetres / 100
Centimetres = Metres x 100

Worked Example

Convert 175 cm to metres:

Start with the value in centimetres: 175 cm
Divide by 100: 175 / 100 = 1.75
Result: 175 cm = 1.75 m

To verify, multiply back: 1.75 m x 100 = 175 cm. The conversion is correct.

Why Divide by 100?

The prefix "centi-" means one hundredth. So a centimetre is one hundredth of a metre. When you move from a smaller unit (cm) to a larger unit (m), you divide. When you move from a larger unit (m) to a smaller unit (cm), you multiply. This is the same logic used across all SI unit conversions (millimetres to metres, metres to kilometres, etc.).

Centimetres, Metres, and Millimetres

Unit	Symbol	Relative to 1 metre
Kilometre	km	1000 m
Metre	m	1 m (base unit)
Centimetre	cm	0.01 m (1/100 of a metre)
Millimetre	mm	0.001 m (1/1000 of a metre)

In everyday use in New Zealand, heights are commonly given in centimetres (for example, a person who is 175 cm tall), while construction and building specifications are usually given in millimetres. Metres are used for room dimensions, land distances, and lengths over about 1 m.
