How to Convert Square Centimetre to Darcy
- 1 cm² = 101324996.6 D
- 1 D = 9.869233 × 10⁻⁹ cm²
- Example: convert 15 cm² to D: 15 cm² = 15 × 101324996.6 D = 1519874949 D
Formula
D = cm² × 101324996.5828
Derivation from SI units:
- 1 cm² = 10⁻⁴ m².
- 1 D passes 1 cm³/s of a 1 cP fluid through 1 cm² under 1 atm/cm: 9.869233 × 10⁻¹³ m².
- 1 cm² = 0.0001 m² ÷ 9.869233 × 10⁻¹³ m² per D = 101324996.5828 D
One unit is a measured value, so the factor is approximate. Square Centimetre definition: square centimetre; Darcy definition: darcy.
Worked examples
- A reading of 0.000000001 cm² converts to 0.1013249966 D.
0.000000001 cm² × 101324996.6 = 0.1013249966 D - A value of 0.000001 cm² is 101.3249966 D.
0.000001 cm² × 101324996.6 = 101.3249966 D

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