How to Convert Hectares to Square Kilometers

To convert a measurement in hectares to a measurement in square kilometers, divide the area by the following conversion ratio: 100 hectares/square kilometer.

Since one square kilometer is equal to 100 hectares, you can use this simple formula to convert:

square kilometers = hectares ÷ 100

The area in square kilometers is equal to the area in hectares divided by 100.

For example, here's how to convert 5 hectares to square kilometers using the formula above.

square kilometers = (5 ha ÷ 100) = 0.05 sq km
