How to Convert Darcy to Square Centimetre
- 1 D = 9.869233 × 10⁻⁹ cm²
- 1 cm² = 101324996.6 D
- Example: convert 15 D to cm²: 15 D = 15 × 9.869233 × 10⁻⁹ cm² = 1.48038495 × 10⁻⁷ cm²
Formula
cm² = D × 9.869233 × 10⁻⁹
or cm² = D ÷ 101324996.5828
Derivation from SI units:
- 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 = 10⁻⁴ m².
- 1 D = 9.869233 × 10⁻¹³ m² ÷ 0.0001 m² per cm² = 9.869233 × 10⁻⁹ cm²
One unit is a measured value, so the factor is approximate. Darcy definition: darcy; Square Centimetre definition: square centimetre.
Worked examples
- A reading of 0.1 D converts to 9.869233 × 10⁻¹⁰ cm².
0.1 D × 9.869233 × 10⁻⁹ = 9.869233 × 10⁻¹⁰ cm² - A value of 2 D is 1.9738466 × 10⁻⁸ cm².
2 D × 9.869233 × 10⁻⁹ = 1.9738466 × 10⁻⁸ cm²

Where it's used
Darcies are used for oil and gas reservoir permeability, 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 darcy?
1 D = 9.869233 × 10⁻⁹ cm².
How do I convert darcies to square centimetres?
Multiply the value in D by 9.869233 × 10⁻⁹, or divide it by 101324996.6. For example, 15 D × 9.869233 × 10⁻⁹ = 1.48038495 × 10⁻⁷ cm².
Is the D to cm² conversion exact?
Not exactly. The darcy is a measured value (see sources). Results are good to about 5 significant figures.
