Hectares to Square Kilometers (ha to km²) Converter

1 hectare (ha) = 0.01 square kilometers (km²). To convert hectares to square kilometers, multiply by 0.01: 2 ha × 0.01 = 0.02 km². Also searched as hectares to square kilometres.

1 ha = 0.01 km²

Quick facts

How to convert hectares to square kilometers

  1. Take the value in hectares.
  2. Multiply it by 0.01 (the number of square kilometers in one hectare).
  3. Round the result to the precision you need.
km² = ha × 0.01

Worked example (a small field): 2 ha × 0.01 = 0.02 km².

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