Hectares to Square Kilometers Converter

About this calculator

The hectare (10,000 m²) is the standard metric unit for measuring land area — farms, forests, parks, and administrative districts — while the square kilometer (1,000,000 m²) is used for larger regions like cities, watersheds, and countries. The two are related by a simple factor of 100: 1 km² = 100 hectares. This calculator converts an area in either direction and also shows the reverse equivalent so you can sanity-check the result.

Farmers, land surveyors, foresters, and urban planners switch between these units constantly — a single field is naturally described in hectares, but when summing up a whole municipality's farmland or forest cover, square kilometers give a more manageable number. News reports on wildfire extent, deforestation, or national land area also commonly need converting between the two depending on the scale being discussed.
