Convert Square centimetres to Hectares
1 square centimetre is 1.00e-8 ha. One square centimetre is exactly 1e-8 hectares.
One square centimetre is 1.0000 × 10^-8 hectares. To convert square centimetres to hectares, multiply by 1.0000 × 10^-8; to go the other way, divide by 1.0000 × 10^-8 or multiply by 100000000. The relation is exact but the figure is not: it is a rounding of a number that does not terminate, and it follows from NIST Office of Weights and Measures. A ten-thousandth of a square metre — not a hundredth, which is the mistake squaring a prefix invites.

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: sqcm to ha is how the symbols are typed on a keyboard with no superscript on it.
How do you convert square centimetres to hectares? The converter and the working
- 1.Take the measurement in square centimetres.
- 2.Multiply by 1.0000 × 10^-8 — that is how many hectares fit in one square centimetre.
- 3.To go back the other way, divide by 1.0000 × 10^-8, or multiply by 100000000.
Worked example: 25 square centimetres to hectares
- Formula
- cm² × 1.0000 × 10^-8 = ha
- Arithmetic
- 25 × 1.0000 × 10^-8 = 2.50e-7 ha
- Answer
- 25 cm² = 2.50e-7 ha
The factor is rounded for display; the figure above is computed from the full value.

What is a square centimetre?
A ten-thousandth of a square metre — not a hundredth, which is the mistake squaring a prefix invites. 10,000 cm² to the square metre.
What is a hectare?
10,000 square meters, or about 2.471 acres. The metric unit of land area.
How many hectares are in a square centimetre?
One square centimetre is 1.0000 × 10^-8 hectares. Going the other way, one hectare is 100000000 square centimetres. 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.
