TOOLConvert area and land units
Switch between metric and imperial area units instantly — square millimeters, centimeters, meters and kilometers alongside square inches, feet, yards, acres and hectares. It's the quick answer for a room, a plot of land, a floor plan or a property listing in unfamiliar units.
Common area conversions
These are based on the exact definitions (1 ft = 0.3048 m, 1 acre = 4046.8564224 m²), so the conversions are precise.
How to convert area by hand
Area conversions are single multiplications by a fixed factor — just note the factors are larger than for length because area is a square measure. Two worked examples:
- 100 square metres to square feet: 100 × 10.7639 = 1,076 ft².
- 1 acre to hectares: 1 × 0.404686 = 0.405 ha (an acre is 4,046.86 m²).
A useful anchor: a square metre is about 10.76 square feet, and a hectare (10,000 m²) is about 2.47 acres.
Area conversions in everyday life
These show up with property and real estate (a home listed in square feet vs square metres), land and gardens (acres vs hectares), and flooring, paint or turf where coverage is quoted in one unit and your room measured in another. Getting the square measure right matters — an error here scales fast because you're dealing with two dimensions at once.
Measuring the room first? Use the length converter for the individual sides, then square up here. You can also switch to the weight or temperature converters.
