Square feet to Square meters

One square feet is 0.092903 square meters, and one square meters is 10.76391 square feet.

The square meter is the SI unit of area. It is used for floor space, land plots and material quantities such as tiles or paint coverage; a parking bay is about 12 square meters.

  • 1 ft²= 0.092903 m²
  • 5 ft²= 0.464515 m²
  • 10 ft²= 0.92903 m²

The square meter is the International System unit of area, the area of a square with one-meter sides. It is the base for all metric area measures.

Apartment and office floor areas, building permits, land in urban plots, solar panel output per unit and fabric are measured in square meters in metric countries. Tiling and flooring quantities follow the same unit.

Square feet to Square kilometers

One square feet is 9.2903e-8 square kilometers, and one square kilometers is 10,763,910.41671 square feet.

A square kilometer is one million square meters. It is used for districts, national parks and country areas — and one square kilometer is exactly 100 hectares.

  • 1 ft²= 9.2903e-8 km²
  • 5 ft²= 4.6452e-7 km²
  • 10 ft²= 9.2903e-7 km²

A square kilometer is the area of a square one kilometer on each side, exactly 1,000,000 square meters or 100 hectares. It is the usual metric unit for large areas.

City and district areas, national parks, reservoirs, islands and administrative regions are measured in square kilometers. Satellite imagery and land-cover studies report extents this way as well.

Square feet to Hectares

One square feet is 9.2903e-6 hectares, and one hectares is 107,639.104167 square feet.

A hectare is 10,000 square meters, or 0.01 square kilometers. It is the standard unit for farmland and land-title areas in Tanzania and most metric countries.

  • 25 ft²= 2.3226e-4 ha
  • 100 ft²= 9.2903e-4 ha
  • 500 ft²= 0.004645 ha

A hectare is exactly 10,000 square meters, the area of a square 100 meters on a side, and it equals 0.01 square kilometers. It is the metric unit of land area.

Farmland, forest, parks and large plots are measured in hectares across most of the world, and land registries in metric countries record titles in hectares. Sports fields and golf courses also appear in hectares.

Square feet to Acres

One square feet is 2.2957e-5 acres, and one acres is 43,560 square feet.

An acre is 4,046.8564224 square meters, about 0.4047 hectares. It is the traditional land unit of the UK and US and is still used for land in parts of East Africa.

  • 5 ft²= 1.1478e-4 ac
  • 10 ft²= 2.2957e-4 ac
  • 25 ft²= 5.7392e-4 ac

An acre is exactly 4,046.8564224 square meters, an area of 4,840 square yards, or one chain by one furlong. It is a unit of area, not of length.

Land titles, farm sizes, plots and ranches are described in acres in the United States, the United Kingdom and parts of the Commonwealth. Estate agents quote plot sizes in acres.

Square feet to Square inches

One square feet is 144 square inches, and one square inches is 0.006944 square feet.

A square inch is 6.4516 square centimeters. It is used for small areas, and is the denominator in psi, the imperial pressure unit.

  • 1 ft²= 144 in²
  • 5 ft²= 720 in²
  • 10 ft²= 1,440 in²

Square feet to Square miles

One square feet is 3.587e-8 square miles, and one square miles is 27,878,400 square feet.

A square mile is about 2.59 square kilometers, or exactly 640 acres. It is used for land and territory areas in the United States and the UK, and for large ranch or park sizes.

  • 1 ft²= 3.587e-8 mi²
  • 5 ft²= 1.7935e-7 mi²
  • 10 ft²= 3.587e-7 mi²

A square mile is the area of a square one mile on each side, exactly 2.589988110336 square kilometers, or exactly 640 acres. It is built from the statute mile and never from the nautical mile.

Metropolitan areas, counties, states, large ranches and national parks are measured in square miles in those countries. Weather maps and watershed studies also report extents in square miles.

What square feet are used for

A square foot is 0.09290304 square meters. It is the standard unit for floor area and property listings in the United States and the UK.

A square foot is the area of a square with sides one foot long, exactly 0.09290304 square meters. It is a unit of area and not a unit of length.

Floor area in property listings, apartment sizes, tiles, paint coverage and roofing are quoted in square feet in the United States and several other markets. Carpets and timber are sold this way too.

The conversion to square meters is exact because the foot is exactly 0.3048 meters and the square of that is 0.09290304. Results are printed rounded, so a square foot figure changed to square meters and back may lose a digit.

A frequent mistake is multiplying a length in feet by itself when only one dimension was measured, or converting a linear foot rate to a square foot rate directly. The two measure different things.

Square feet measure rooms and buildings, square meters do the same on metric plans, and acres measure land. A square meter is about 10.76 square feet, so a floor area quoted in the wrong unit is off by roughly a factor of ten.

Every factor is an exact definition, so the only loss is display rounding. Land figures quoted in acres and hectares are usually rounded at the source.

Area factors are the square of the corresponding length factors, so the numbers move much faster than a reader expects. A square meter contains 10,000 square centimeters, and a square kilometer a million square meters, not a thousand.

The units that share a name across systems are still different sizes: a square mile and a square kilometer differ by a factor of about 2.59, and an acre is a fixed area rather than a square with equal sides, so it does not convert like the length units it is named after.

Land is where the reciprocal matters most, because acres and hectares are both in use for the same plots. When a figure moves between them, check it against a shape you can picture — a hectare is a square 100 meters on each side — rather than against the number alone.
