Convert Square Kilometres to Hectares (km2 to ha)
1 square kilometre (km²) = 100 hectares (ha). 1 ha = 0.01 km². Example: 15 km² = 15 × 100 = 1500 ha.

How to Convert Square Kilometre to Hectare
- 1 km² = 100 ha
- 1 ha = 0.01 km²
- Example: convert 15 km² to ha: 15 km² = 15 × 100 ha = 1500 ha
Formula
ha = km² × 100
Derivation from SI units:
- 1 km² = (1000 m)² = 10⁶ m² = 100 ha
- 1 ha = 100 m × 100 m = 10 000 m² (a non-SI unit accepted for use with the SI)
- 1 km² = 1000000 m² ÷ 10000 m² per ha = 100 ha
Both units are defined exactly, so the factor is exact. Square Kilometre definition: square kilometre; Hectare definition: hectare.
Worked examples
- A reading of 2 km² converts to 200 ha.
2 km² × 100 = 200 ha - A value of 50 km² is 5000 ha.
50 km² × 100 = 5000 ha
