How to Convert Square Centimeter to Square Meter
- 1 cm² = 0.0001 m²
- 1 m² = 10000 cm²
- Example: convert 15 cm² to m²: 15 cm² = 15 × 0.0001 m² = 0.0015 m²
Formula
m² = cm² ÷ 10000
Derivation from SI units:
- 1 cm² = (0.01 m)² = 10⁻⁴ m²
- 1 m² = 1 m × 1 m
Both units are defined exactly, so the factor is exact. Square Centimeter definition: square centimeter; Square Meter definition: square meter.
Worked examples
- An ISO 9237 test area of 20 cm² is 0.002 m².
20 cm² × 0.0001 = 0.002 m² - 10000 cm² is exactly 1 m².
10000 cm² × 0.0001 = 1 m²

Where it's used
To calculate a face velocity in m/s from a flow in m³/s, the test area must be in m²: divide cm² by 10 000.
