How to convert areas
- Type the value.
- Choose the From and To units from square centimeters, square meters, hectares, square kilometers, square inches, square feet, square yards, acres and square miles.
- Read the result, the exact factor, and the table of the same area in every unit.
How it works
Each unit is stored as an exact number of square meters. Square units of length are the length factor squared, so a square foot is 0.3048 × 0.3048 = 0.09290304 m².
| Unit | Exact size in m² |
|---|---|
| square inch | 0.00064516 |
| square foot | 0.09290304 |
| square yard | 0.83612736 |
| acre | 4,046.8564224 |
| hectare | 10,000 |
| square mile | 2,589,988.110336 |
A common slip is to convert length factors without squaring them. One meter is 3.28 feet, but one square meter is 10.76 square feet, not 3.28.
Worked example
A plot is listed as 2,400 square feet. What is it in square meters, acres and hectares?
- Square meters: 2,400 × 0.09290304 = 222.97 m².
- Acres: 2,400 ÷ 43,560 = 0.0551 acres.
- Hectares: 222.97 ÷ 10,000 = 0.0223 ha.
Set From to square feet and To to square meters, and the table shows all of them together.
Area facts
- 1 acre is 43,560 square feet and 640 acres make a square mile.
- A football pitch is about 0.7 hectares.
- Indian property listings often use square feet, while maps and records can use hectares, so conversions appear a lot.
Popular pairs
Try sq ft to sq m or acres to hectares for ready tables. For volumes and capacities, use the volume converter, and for lengths, the length converter.
