Convert land or room area into square meters, hectares, ares, acres and other square units.
Use a point or comma for decimals.
Area
Area has two dimensions. Since 1 m = 100 cm, a square with a side of 1 m has an area of 100 cm × 100 cm, or 10,000 cm². A length conversion factor therefore cannot be used directly for area.
result = value × starting unit factor in m² ÷ target unit factor in m²
| Starting area | Equivalent area |
|---|---|
| 1 km² | 1,000,000 m² |
| 1 ha (hectare) | 10,000 m² |
| 1 a (are) | 100 m² |
| 1 ha | 100 a |
| 1 m² | 10,000 cm² |
| 1 ft² | 0.09290304 m² |
| 1 acre | 4,046.8564224 m² |
The converter changes the unit of an existing area. For a rectangular plot, first calculate length × width with both lengths in the same unit. Hectares and ares are metric area units; the acre here uses the international foot.
A plot of 25 ares has an area of 2,500 m², or 0.25 ha. For 2 hectares, multiply by 10,000 to get 20,000 m².
