Acreage Calculator
Working out the size of a piece of land in acres is a common need when buying or selling a section, sizing a paddock, planning a lifestyle block or simply making sense of a listing, and this calculator does it instantly from the dimensions. Enter the length and width of the area, choose whether you are measuring in metres or feet, and it returns the size in acres, hectares and square metres all at once, updating as you type. The maths for a rectangular block is simple: multiply length by width to get the area, then convert. The conversions are where the calculator earns its keep, because the units come from different systems and the factors are easy to forget. One acre is 4,046.86 square metres, a hectare is 10,000 square metres, and so one hectare works out to about 2.47 acres. New Zealand officially uses hectares and square metres, but acres still turn up constantly in conversation, in older titles and in listings, especially for rural and lifestyle property, so being able to flip between them removes a lot of confusion. Seeing all three figures side by side also helps you picture the size, since most people have a feel for one unit but not the others. The tool handles feet as well as metres, which is handy when working from imperial measurements or overseas figures, converting them before calculating. That makes it genuinely useful for buyers and sellers comparing sections and blocks, for farmers, growers and lifestylers sizing paddocks and plantings, for fencing, spraying and seeding estimates, and for anyone translating a land area between acres, hectares and square metres. For an irregular block, measure it as rectangles and add the areas. The conversions and a worked example are explained clearly below.
How it works
The area is length times width. If measured in feet, each dimension is converted to metres by multiplying by 0.3048 first. The area in square metres is then divided by 4,046.856 for acres and by 10,000 for hectares.
Worked example
A block 100 metres by 100 metres has an area of 10,000 square metres. Dividing by 4,046.86 gives about 2.47 acres, and dividing by 10,000 gives exactly 1 hectare. So a one hectare block is just under two and a half acres.
