Darcy to square meters
Type a value in D to get it in m² instantly.
9.869×10⁻¹¹m²
That's 1,000× as permeable as reservoir sandstone, while clean gravel is 10× higher. For water that is a hydraulic conductivity of about 9.66 cm/s.
Convert the other way: m² to D
What it means
How well does it flow?
Hydraulic conductivity assumes water at 20 °C. For oil or gas the same rock gives a different figure.
The math
How to convert D to m²
To convert darcy to square meters, multiply by 9.869×10⁻¹³.
Example: 100 D × 9.869×10⁻¹³ = 9.869×10⁻¹¹ m².
In the other direction, 1 m² = 1.013×10¹² D.
