Area Converter

How to use it

Area conversions here run through the square meter as the base unit. Metric area units scale the way you'd expect from length: a square kilometer is a million square meters (1,000² = 1,000,000), and a hectare is defined directly as 10,000 square meters — originally meant to represent a 100 m × 100 m plot, which is why it's a convenient unit for farmland. The imperial and US units are trickier because they come from squaring a length unit that isn't a round number in meters. One square foot is 0.09290304 m² (0.3048² ), so one square meter is about 10.764 square feet (1 ÷ 0.09290304 ≈ 10.764) — not 10 or 11, which surprises people converting room sizes. An acre is defined as 43,560 square feet, which works out to 4,046.8564224 square meters, or roughly 0.4047 hectares. Worked example: converting a 500 m² plot to acres: 500 ÷ 4046.8564224 ≈ 0.1236 acres. Converting 2 acres to hectares: 2 × 4046.8564224 = 8093.7 m², or 8093.7 ÷ 10,000 = 0.809 hectares. A useful mental anchor: a hectare and an acre are similar in scale (a hectare is about 2.47 acres), which is why both show up on international real estate and agriculture listings. But square feet and square meters are not close — a 1,500 sq ft house is only about 139 m², so don't assume the numbers are roughly interchangeable the way, say, kilometers and miles loosely are. Always check which unit a floor plan or land listing uses before comparing two properties.

Frequently asked questions

How many square feet are in a square meter?

About 10.764 square feet. This comes from squaring the foot-to-meter ratio (1 foot = 0.3048 m, and 0.3048² ≈ 0.0929, so 1 ÷ 0.0929 ≈ 10.764). It's a bigger jump than people expect from the linear 3.28 ft-per-meter ratio, since area scales by the square.

How many acres are in a hectare?

One hectare is about 2.471 acres. A hectare is a clean 10,000 square meters, while an acre comes from an old British definition (43,560 square feet, or about 4,046.86 square meters), so the ratio between them isn't a round number even though both are common on land listings.

Why isn't an acre a round number of square meters?

Because an acre was originally defined as the area a team of oxen could plow in a day — 1 furlong (660 ft) by 1 chain (66 ft) — not designed around the metric system. That historical origin is why it converts to an irregular 4,046.86 m² instead of a clean number.

Can I convert square units the same way as linear units (just square the factor)?

Yes — an area conversion factor is always the linear factor squared. This converter already does that internally, so you don't need to calculate it yourself, but it's why, for example, the m²-to-ft² factor (10.764) is roughly the square of the m-to-ft factor (3.281² ≈ 10.77, close but not identical due to rounding).
