Convert Square kilometres to Hectares
1 square kilometre is 100 ha. One square kilometre is exactly 100 hectares.
One square kilometre is 100 hectares. To convert square kilometres to hectares, multiply by 100; to go the other way, divide by 100 or multiply by 0.01. The factor is exact rather than rounded: it follows from NIST Office of Weights and Measures. A million square metres, or 100 hectares.

Factors are entered by hand from NIST Office of Weights and Measures rather than derived from a units library, so the ones that terminate are exact rather than rounded.
The same converter answers this pair however it is written: sqkm to ha is how the symbols are typed on a keyboard with no superscript on it.
How do you convert square kilometres to hectares? The converter and the working
- 1.Take the measurement in square kilometres.
- 2.Multiply by 100 — that is how many hectares fit in one square kilometre.
- 3.To go back the other way, divide by 100, or multiply by 0.01.
Worked example: 25 square kilometres to hectares
- Formula
- km² × 100 = ha
- Arithmetic
- 25 × 100 = 2,500 ha
- Answer
- 25 km² = 2,500 ha
The factor is exact, so this figure is exact too — only the display is rounded.
