How area conversion works

Every area unit converts through a single base - here it is the square meter. Convert your figure to square meters first, then divide by the target unit's size. The tool does both steps live as you type. The exact factors it uses are:

  • 1 square foot = 0.092903 m2 (a foot is 0.3048 m, and 0.3048 squared is 0.092903)
  • 1 square yard = 0.836127 m2 (nine square feet)
  • 1 acre = 4,046.86 m2 = 43,560 ft2
  • 1 hectare = 10,000 m2 = 2.4711 acres
  • 1 square kilometer = 1,000,000 m2 = 100 hectares

Real-world sizes to picture

Area numbers are hard to feel until you anchor them to something familiar. A hectare is close to a rugby pitch; an acre is a touch smaller than a full football pitch. The table below gives you a few reference points for property, sport and land.

Acres, hectares and land

For land and property, acres and hectares dominate. An acre began life as the area a team of oxen could plough in a day - one furlong long by one chain wide - which is why it is an odd 4,047 m2 rather than a round number. A hectare is deliberately tidy: a 100 m by 100 m square. When you read a listing, estate agents often quote gardens in square feet, farmland in acres, and development plots in hectares, so being able to flip between all three quickly is the whole point of a converter like this.

Where people get caught out

The classic mistake is scaling a linear conversion into an area. If a room is measured in feet and you want square meters, you cannot just multiply the length by 0.3048 - you multiply the area by 0.092903, because both dimensions shrink. Doubling a room's width and length quadruples its floor area, it does not double it. A second trap is unit shorthand: "sq ft" and "ft2" mean the same thing, but "linear feet" does not - that measures a single edge, not an area. Working with length instead? Try the length converter. Need volume for concrete or soil? The volume converter handles cubic units, and the all-in-one unit converter covers everything in one place.

Frequently asked questions

How many square feet are in a square meter?
One square meter equals 10.7639 square feet. To go the other way, one square foot is 0.092903 square meters. So a 50 square meter flat is about 538 square feet.
How big is one acre?
One acre is 4,046.86 square meters, or 43,560 square feet, or about 0.4047 hectares. It is roughly the size of a standard football (soccer) pitch, though a full pitch is a bit larger at around 1.76 acres.
How many acres are in a hectare?
One hectare is 10,000 square meters, which equals 2.4711 acres. Conversely, one acre is 0.4047 hectares. Hectares are the metric standard for land area; acres are still common in the US and UK.
How do I convert square feet to acres?
Divide the square footage by 43,560. For example, a 10,000 square foot lot is 10,000 / 43,560 = 0.2296 acres.
What is the difference between a square kilometer and a hectare?
A square kilometer is 100 hectares, or 1,000,000 square meters. A hectare is 10,000 square meters, so it takes 100 hectares to make one square kilometer.
