Acres vs. Hectares
The acre is an imperial unit used mainly in the US and UK; the hectare is the metric unit used across most of the world for land. One hectare is a square 100 m × 100 m (10,000 m²), which works out to just under two and a half acres.
| Unit | Equal to |
|---|---|
| 1 acre | 4,047 m² = 0.4047 ha = 43,560 ft² |
| 1 hectare | 10,000 m² = 2.4711 acres = 107,639 ft² |
