Convert Square Centimetres to Square Metres (cm2 to m2)
1 square centimetre (cm²) = 0.0001 square metres (m²). 1 m² = 10000 cm². Example: 15 cm² = 15 × 0.0001 = 0.0015 m².

How to Convert Square Centimetre to Square Metre
- 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 = 10⁻⁴ m².
- Intrinsic permeability k has dimension of area: k = K μ / (ρ g).
Both units are defined exactly, so the factor is exact. Square Centimetre definition: square centimetre; Square Metre definition: square metre.
Worked examples
- A reading of 0.000000001 cm² converts to 1 × 10⁻¹³ m².
0.000000001 cm² × 0.0001 = 1 × 10⁻¹³ m² - A value of 0.000001 cm² is 1 × 10⁻¹⁰ m².
0.000001 cm² × 0.0001 = 1 × 10⁻¹⁰ m²

Where it's used
Square Centimetres are used for soil physics and older literature, while square metres appear in reservoir and porous-media flow. Both measure intrinsic permeability of a porous medium, so the conversion is a fixed factor.

Frequently asked questions
How many square metres are in 1 square centimetre?
1 cm² = 0.0001 m².
How do I convert square centimetres to square metres?
Multiply the value in cm² by 0.0001, or divide it by 10000. For example, 15 cm² × 0.0001 = 0.0015 m².
Is the cm² to m² conversion exact?
Yes. Both units are defined exactly, and 1 cm² is exactly 0.0001 m².
