Hectares to square kilometers Conversion
1 hectares (hectare) is equal to 0.01 square kilometers (km²).
1 hectare = 0.01 km²
or
1 km² = 100 hectare
Formula
To convert a area from hectares (hectare) to square kilometers (km²), divide the area in hectares by 100
a(km²) = a(hectare) / 100
Examples:
Convert 100 hectares to square kilometers:
a(km²) = 100hectare / 100 = 1 km²
