How to Convert Hectare to Square Meter
- 1 ha = 10000 m²
- 1 m² = 0.0001 ha
- Example: convert 1 ha to m²: 1 ha = 1 × 10000 m² = 10000 m²
Formula
m² = ha × 10000
Derivation from SI units:
- 1 ha = 100 m × 100 m = 10 000 m² (a non-SI unit accepted for use with the SI)
- 1 m² = 1 m × 1 m
Both units are defined exactly, so the factor is exact. Hectare definition: hectare; Square Meter definition: square meter.
Worked examples
- 1 ha is 10000 m².
1 ha × 10000 = 10000 m² - Half a hectare, 0.5 ha, is 5000 m².
0.5 ha × 10000 = 5000 m²
