Square Centimetres to Square Micrometres (cm2 to um2)
1 square centimetre (cm²) = 100000000 square micrometres (µm²). 1 µm² = 1 × 10⁻⁸ cm². Example: 15 cm² = 15 × 100000000 = 1500000000 µm².

How to Convert Square Centimetre to Square Micrometre
- 1 cm² = 100000000 µm²
- 1 µm² = 1 × 10⁻⁸ cm²
- Example: convert 15 cm² to µm²: 15 cm² = 15 × 100000000 µm² = 1500000000 µm²
Formula
µm² = cm² × 100000000
Derivation from SI units:
- 1 cm² = 10⁻⁴ m².
- 1 µm² = 10⁻¹² m², almost exactly one darcy (1 D = 0.9869 µm²).
- 1 cm² = 0.0001 m² ÷ 1 × 10⁻¹² m² per µm² = 100000000 µm²
Both units are defined exactly, so the factor is exact. Square Centimetre definition: square centimetre; Square Micrometre definition: square micrometre.
Worked examples
- A reading of 0.000000001 cm² converts to 0.1 µm².
0.000000001 cm² × 100000000 = 0.1 µm² - A value of 0.000001 cm² is 100 µm².
0.000001 cm² × 100000000 = 100 µm²

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