25 ha = 0.25 km2. To convert hectares to square kilometers, divide by 100: 25 ÷ 100 = 0.25.
How to convert hectares to square kilometers
km2 = ha × 0.01
- 1 ha = 0.01 km2 (and 1 km2 = 100 ha).
- Multiply the amount by the factor: 25 × 0.01 = 0.25.
- Answer: 25 ha = 0.25 km2.
Shortcut: dividing by 100 gives the same result as multiplying by 0.01.
