Square feet, square metres, acres and hectares for flats, rooms, plots and farmland
Square feet, square metres, acres and hectares for flats, rooms, plots and farmland. No data leaves your browser – every conversion happens locally.
Why area conversions trip people up
Area units square the length factor. One foot is 0.3048 m, so one square foot is 0.3048 × 0.3048 = 0.0929 m². The classic mistake is multiplying square metres by 3.281 (the feet-per-metre figure) and getting a number about ten times too small.
Land units are fixed too: a hectare is 10,000 m² and an acre is 4,046.86 m². In India, a gaj is the same as a square yard, so the square yard option covers it. Bigha and guntha aren't included because their size changes from state to state.
Common area conversions
| 1 acre | 4,047 m² |
| 1 hectare | 10,000 m² |
| 1 sq mile | 2.59 km² |
| 1 sq ft | 0.0929 m² |
| 100 sq ft | 9.29 m² |
| 1,000 sq ft | 92.9 m² |
Worked examples
A 1,200 sq ft flat
That's 111.48 m². Builders in India often quote super built-up area, so the carpet area you actually walk on is usually 20–30% less.
Farm land
2 acres is 0.81 hectares. Government land records in many countries use hectares even when locals talk in acres.
Flooring a room
A 4 × 5 m room is 20 m², or 215.3 sq ft. Add 5–10% for cutting waste when you order tiles.
Flat and house sizes in square feet, metres and yards
Property listings in India and the US quote square feet, most other countries quote square metres, and plots in north India are often sold by the gaj (square yard). Each row multiplies by 0.0929 for m² and divides by 9 for square yards.
| Square feet | Square metres | Square yards (gaj) |
|---|---|---|
| 500 sq ft | 46.5 m² | 55.6 sq yd |
| 750 sq ft | 69.7 m² | 83.3 sq yd |
| 1,000 sq ft | 92.9 m² | 111.1 sq yd |
| 1,200 sq ft | 111.5 m² | 133.3 sq yd |
| 1,500 sq ft | 139.4 m² | 166.7 sq yd |
| 2,000 sq ft | 185.8 m² | 222.2 sq yd |
| 2,500 sq ft | 232.3 m² | 277.8 sq yd |
Rounding and odd-shaped rooms
Rounding the factor costs more than you'd think on large areas. A hectare (10,000 m²) is 107,639 sq ft. Use 10.76 instead of 10.7639 and you lose 39 sq ft, roughly the size of a small bathroom. Let the tool do it, since it uses the full factor.
For L-shaped or irregular rooms, split the floor into rectangles, work out each one, and add them up. Don't measure the longest length and the longest width and multiply. That overstates the area of an L-shaped room by the whole missing corner.
