Converting the other way: square kilometers to hectares

hectares = square kilometers × 100. So 3 square kilometers is back to 300 hectares; one square kilometer is 100 hectares. See the square kilometers to hectares table.

Quick estimate in your head

For a rough answer, multiply by about 0.01: 300 × 0.01 ≈ 3 km2, against the exact 3 km2 (0.0% out). Good enough to check that a calculated result is sensible.

Common mistakes

The usual slip is using the factor the wrong way round. A hectare is smaller than a square kilometer, so the number of square kilometers must come out smaller than the number of hectares. If your answer goes the other way, divide instead of multiplying.
