How to Convert Square Metre to Darcy
- 1 m² = 1013249966000 D
- 1 D = 9.869233 × 10⁻¹³ m²
- Example: convert 0.000000000001 m² to D: 0.000000000001 m² = 0.000000000001 × 1013249966000 D = 1.013249966 D
Formula
D = m² × 1013249965828
Derivation from SI units:
- Intrinsic permeability k has dimension of area: k = K μ / (ρ g).
- 1 D passes 1 cm³/s of a 1 cP fluid through 1 cm² under 1 atm/cm: 9.869233 × 10⁻¹³ m².
One unit is a measured value, so the factor is approximate. Square Metre definition: square metre; Darcy definition: darcy.
Worked examples
- 0.000000000001 m² is 1.013249966 D.
0.000000000001 m² × 1013249966000 = 1.013249966 D - A tight sand of 0.00000000000001 m² is 0.01013249966 D.
0.00000000000001 m² × 1013249966000 = 0.01013249966 D

Frequently asked questions
How many darcies is 1 m²?
1 m² = 1013249966000 D, an enormous permeability; real rocks are around 10⁻¹² m² (about 1 D) or less.
How many darcies are in 1 square metre?
1 m² = 1013249966000 D.
How do I convert square metres to darcies?
Multiply the value in m² by 1013249966000. For example, 0.000000000001 m² × 1013249966000 = 1.013249966 D.
Is the m² to D conversion exact?
Not exactly. The darcy is a measured value (see sources). Results are good to about 5 significant figures.
