How to use the area converter
- 1 Type the value you want to convert.
- 2 Choose the unit to convert from and the unit to convert to.
- 3 Press ⇄ to swap the two units.
- 4 Read the result, and see the same area in every other unit in the table below.
Getting area conversions right
Area units are squares of length units, so their factors are squared too: 1 m is 3.28 ft, but 1 m² is 10.76 sq ft. Measure each side in one unit, multiply, then convert the total. For square feet and metres alone, Square Feet to Square Meters is quicker, and for acres Acres to Square Feet.
- Hectares are common for farms in metric countries; acres in the US, UK and South Asia.
- For local land units, use Marla to Square Feet with the right marla size.
- Round only the final answer to avoid adding errors.

Farms and land
Convert acres to hectares for farm records and grants. 10 acres is 4.05 hectares. For acres in square feet, see Acres to Square Feet.
Flooring and painting
Work out how many square metres of tiles or paint you need from a room measured in square feet, then add about 10% for cutting and waste.
Maps and geography
