Square Kilometers to Hectares (km² to ha) Converter
1 square kilometer equals 100 hectares — multiply the number of square kilometers by 100 to convert. This is an exact conversion, so 5 km² is 500 hectares and 10 km² is 1,000 hectares.
The formula
To convert square kilometers to hectares, multiply by 100:
hectares = square kilometers × 100
For example, 7.5 km² × 100 = 750 ha. To reverse it, divide hectares by 100 (or multiply by 0.01). Because a hectare is 10,000 m² and a square kilometer is 1,000,000 m², exactly 100 hectares fit in one km².
