Convert source value to square metres, then divide by target unit square-metre factor: target = value × source factor ÷ target factor.
| Unit | Square metres for each unit |
|---|---|
| Square metre (m²) | 1 |
| Square foot (ft²) | 0.09290304 |
| Acre | 4,046.8564224 |
| Mu | 666.6667 |
The square-foot and acre factors na exact international definitions. Mu factor 666.6667 m² na the common Chinese definition (1 mu = 2000/3 m², rounded here). Local land units and land-registration units fit use other definitions.
Example wey show the calculation
100 m² ÷ 0.09290304 m²/ft² = 1,076.391042 ft². The same 100 m² na 100 ÷ 4,046.8564224 = 0.024711 acre, and 100 ÷ 666.6667 = 0.150000 mu (display show 0.15 after rounding; value before rounding na 0.14999999 because dem don round the mu factor itself).
