Millidarcy to darcy
Type a value in mD to get it in D instantly.
0.1D
That's about the same as reservoir sandstone. For water that is a hydraulic conductivity of about 0.00966 cm/s.
Convert the other way: D to mD
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 mD to D
To convert millidarcy to darcy, multiply by 0.001.
Example: 100 mD × 0.001 = 0.1 D.
In the other direction, 1 D = 1,000 mD.
