Convert Square centimetres to Square meters
1 square centimetre is 0.0001 m². One square centimetre is exactly 0.0001 square meters.
One square centimetre is 1.0000 × 10^-4 square meters. To convert square centimetres to square meters, multiply by 1.0000 × 10^-4; to go the other way, divide by 1.0000 × 10^-4 or multiply by 10000. 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: square centimetres to square metres is the British spelling of the same units — the metre and the litre are spelled that way outside the United States and the quantity does not change, and sqcm to sqm is how the symbols are typed on a keyboard with no superscript on it.
How do you convert square centimetres to square meters? The converter and the working
- 1.Take the measurement in square centimetres.
- 2.Multiply by 1.0000 × 10^-4 — that is how many square meters fit in one square centimetre.
- 3.To go back the other way, divide by 1.0000 × 10^-4, or multiply by 10000.
Worked example: 25 square centimetres to square meters
- Formula
- cm² × 1.0000 × 10^-4 = m²
- Arithmetic
- 25 × 1.0000 × 10^-4 = 0.0025 m²
- Answer
- 25 cm² = 0.0025 m²
The factor is rounded for display; the figure above is computed from the full value.

10,000 square centimetres to the square metre, not 100
The prefix divides the length and the area squares it, so a hundredth of a metre gives a ten-thousandth of a square metre. The same trap runs through the whole family: 1,000,000 mm² to the m², and a square kilometre is a million square metres rather than a thousand. Doubling a room’s side quadruples its floor, and this is that fact written in prefixes.

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 square meter?
A meter on a side, and about 10.764 square feet.
How many square meters are in a square centimetre?
One square centimetre is 1.0000 × 10^-4 square meters. Going the other way, one square meter is 10000 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.
