Convert Square Metres to Square Centimetres (m2 to cm2)
1 square metre (m²) = 10000 square centimetres (cm²). 1 cm² = 0.0001 m². Example: 15 m² = 15 × 10000 = 150000 cm².

How to Convert Square Metre to Square Centimetre
- 1 m² = 10000 cm²
- 1 cm² = 0.0001 m²
- Example: convert 15 m² to cm²: 15 m² = 15 × 10000 cm² = 150000 cm²
Formula
cm² = m² × 10000
Derivation from SI units:
- Intrinsic permeability k has dimension of area: k = K μ / (ρ g).
- 1 cm² = 10⁻⁴ m².
Both units are defined exactly, so the factor is exact. Square Metre definition: square metre; Square Centimetre definition: square centimetre.
Worked examples
- A reading of 0.000000000001 m² converts to 1 × 10⁻⁸ cm².
0.000000000001 m² × 10000 = 1 × 10⁻⁸ cm² - A value of 0.000000001 m² is 0.00001 cm².
0.000000001 m² × 10000 = 0.00001 cm²

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

Frequently asked questions
How many square centimetres are in 1 square metre?
1 m² = 10000 cm².
How do I convert square metres to square centimetres?
Multiply the value in m² by 10000. For example, 15 m² × 10000 = 150000 cm².
Is the m² to cm² conversion exact?
Yes. Both units are defined exactly, and 1 m² is exactly 10000 cm².
