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.

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.
