Convert Hectares to Square kilometres
1 hectare is 0.01 km². One hectare is exactly 0.01 square kilometres.
One hectare is 0.01 square kilometres. To convert hectares to square kilometres, multiply by 0.01; to go the other way, divide by 0.01 or multiply by 100. The factor is exact rather than rounded: it follows from NIST Office of Weights and Measures. 10,000 square meters, or about 2.471 acres.

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: ha to sqkm is how the symbols are typed on a keyboard with no superscript on it.
How do you convert hectares to square kilometres? The converter and the working
- 1.Take the measurement in hectares.
- 2.Multiply by 0.01 — that is how many square kilometres fit in one hectare.
- 3.To go back the other way, divide by 0.01, or multiply by 100.
Worked example: 25 hectares to square kilometres
- Formula
- ha × 0.01 = km²
- Arithmetic
- 25 × 0.01 = 0.25 km²
- Answer
- 25 ha = 0.25 km²
The factor is exact, so this figure is exact too — only the display is rounded.

What is a hectare?
10,000 square meters, or about 2.471 acres. The metric unit of land area.
What is a square kilometre?
A million square metres, or 100 hectares. The unit land area and population density are published in everywhere except the US.
How many square kilometres are in a hectare?
One hectare is 0.01 square kilometres, exactly. Going the other way, one square kilometre is 100 hectares. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
