Frequently Asked Questions

How do I convert square feet to square meters?

To convert square feet to square meters, multiply by 0.092903. For example, 100 sq ft = 100 × 0.092903 = 9.29 m².

How big is an acre in square meters?

One acre equals 4046.86 square meters or 43,560 square feet. This is commonly used for land measurements.

What is the difference between a hectare and an acre?

One hectare equals 10,000 square meters (2.47 acres). Hectares are commonly used in metric countries, while acres are used in the US and UK.

Area measures the size of a two-dimensional surface, like the floor of a room, a plot of farmland, or a country's territory. The area-converter on this page handles the units that come up most often: square meters (m²), square kilometers (km²), hectares (ha), acres, square feet (ft²), square yards (yd²), and square miles (mi²).

The metric side is built on powers of a hundred, since each length unit gets squared. One square meter is the area of a square 1 m on a side, one square kilometer is 1,000 m × 1,000 m, and one hectare is exactly 10,000 m², defined so that 100 hectares fit in one square kilometer. A useful rule of thumb: 1 hectare is about 2.471 acres, and 1 acre is about 0.4047 ha. For everyday sizes, an NBA basketball court is about 420 m² (0.042 ha) and a soccer pitch is around 7,000 m² (0.7 ha).

Two non-metric units dominate real-world use in the US and UK. The acre, used in real estate and agriculture, is 43,560 ft² or 4,046.86 m², a unit that traces back to medieval English land measurement as one chain by one furlong. The square foot is the standard unit for apartment and house size in the US, with a typical studio around 500 ft² and a single-family home around 2,000 ft². Square miles are used for large regions: the city of San Francisco is about 47 mi², and the state of Rhode Island is about 1,545 mi².

A few reference values that are useful in real estate and land work: 1 acre = 43,560 ft² = 4,046.86 m² = 0.404686 ha; 1 hectare = 2.47105 acres = 107,639 ft²; 1 mi² = 640 acres = 2.58999 km²; 1 km² = 0.38610 mi² = 100 ha. For converting plot size in a listing, multiply acres by 0.404686 to get hectares, or by 4,046.86 to get square meters.

The form accepts any field and updates the others at the same precision. A 5-acre lot, for example, is 2.0234 ha, 20,234 m², or 0.007813 mi². The converter keeps the same number of significant figures throughout, so a 1 ft² input shows in m² to four decimal places rather than rounding to 0.

How to use

Type a value in any of the supported fields, including m², km², ha, acre, ft², yd², or mi².
Read the matching values in the other units, updated automatically to the same precision.
Use acres or square feet for US real estate and hectares or square meters for international and scientific use.
Use the swap and clear controls to reset the form for a new conversion.

Formula

1 acre = 43,560 ft² = 4,046.86 m² = 0.404686 ha. 1 hectare = 10,000 m² = 2.47105 acres = 107,639 ft². 1 mi² = 640 acres = 2.58999 km². 1 km² = 100 ha = 0.38610 mi². 1 ft² = 0.092903 m².

Interpreting your results

For US home listings, square feet is the standard, and an apartment described as '800 sq ft' refers to interior floor area, not lot size. For US land, lots are quoted in acres or square feet, while most of the world uses square meters and hectares. For national parks and large regions, square miles and square kilometers are the common units, with 1 mi² ≈ 2.59 km². When comparing two plots, normalize to the same unit before dividing.

Frequently asked questions

How many square feet are in an acre?

One acre equals 43,560 square feet exactly, or 4,046.86 square meters. A 0.25-acre lot, often called a quarter acre, is 10,890 ft², roughly the footprint of a 100 × 100 foot square. This is the standard reference for US suburban land.

What is a hectare?

A hectare is 10,000 square meters, which is the area of a 100 m × 100 m square. It is the standard unit for land area in most countries outside the US and equals 2.471 acres. A 1-hectare plot is about the size of a small city block in many European cities.

How big is a square mile in km?

One square mile equals 2.58999 square kilometers, or about 2.59 km². To convert square miles to km², multiply by 2.59; to go the other way, divide by 2.59. For reference, the borough of Manhattan is about 22.83 mi² or 59.13 km².
