Quick facts

How to convert square kilometers to hectares

  1. Take the value in square kilometers.
  2. Multiply it by 100 (the number of hectares in one square kilometer).
  3. Round the result to the precision you need.
ha = km² × 100

Worked example: 25 km² × 100 = 2500 ha.

To convert hectares back to square kilometers, multiply by 0.01, or divide by 100.
