How to Convert Hectares to Square Kilometers

Calculators can be used to convert measurements from one unit to another

To convert a hectare measurement to a square kilometer measurement, multiply the area by the conversion ratio. One hectare is equal to 0.01 square kilometers, so use this simple formula to convert:

square kilometers = hectares × 0.01

The area in square kilometers is equal to the hectares multiplied by 0.01.

For example, here's how to convert 5 hectares to square kilometers using the formula above.
5 ha = (5 × 0.01) = 0.05 sq km

Hectares and square kilometers are both units used to measure area. Keep reading to learn more about each unit of measure.

Hectares

One hectare is equal to 10,000 square meters, or the area of a square with 100 meter sides.

The hectare is an SI accepted unit for area for use with the metric system. In the metric system, "hecto" is the prefix for 102. Hectares can be abbreviated as ha, for example 1 hectare can be written as 1 ha.

Square Kilometers
