Conversion factors
Imperial area units are squares of the international foot (0.3048 m), so the factors below are exact.
| Unit | In square meters | Relation |
|---|---|---|
| 1 square inch (in²) | 0.00064516 m² | 6.4516 cm² |
| 1 square foot (ft²) | 0.09290304 m² | 144 in² |
| 1 square yard (yd²) | 0.83612736 m² | 9 ft² |
| 1 acre (ac) | 4,046.8564224 m² | 43,560 ft² |
| 1 square mile (mi²) | 2,589,988.110336 m² | 640 acres |
| 1 are (a) | 100 m² | 10 m × 10 m |
| 1 hectare (ha) | 10,000 m² | 100 ares |
| 1 pyeong | 400/121 m² ≈ 3.3058 m² | Korean unit for floor and land area |
Examples
- A 2,000 sq ft house is about 185.81 m².
- A 1-acre lot is 43,560 sq ft, or about 0.405 ha.
- A hectare is about 2.471 acres.
- A soccer pitch of 105 m × 68 m covers 7,140 m², about 1.76 acres.
Things to keep in mind
- Area scales with the square of length: 1 m is 3.28 ft, but 1 m² is 10.76 ft². Convert lengths first with the length converter if you only have dimensions.
- Some older US land records use the survey foot, which differs from the international foot by about 2 parts per million — negligible for most purposes.
- Korean listings quote apartment sizes in pyeong; the pyeong calculator handles exclusive versus supply area.
