Formula

Formula
nD = µD × 1000

Multiply any value in microdarcy by 1000 to obtain the value in nanodarcy.

Worked example

Convert 1 µD to nD.

  1. 01Start with 1 µD.
  2. 02Multiply by the conversion factor: 1 × 1000 = 1000 nD.
Result1 µD = 1000 nD

FAQ

What is the conversion factor from µD to nD?
1 µD equals 1000 nD. To convert, multiply the value in microdarcy by 1000.
How do I convert 1 µD to nD?
1 µD = 1000 nD. For any value, multiply by 1000.
How do I convert nD back to µD?
Divide by the same factor — or equivalently, multiply by 0.001. So 1 nD = 0.001 µD.
When would I need to convert microdarcy to nanodarcy?
Permeability conversions between µD and nD appear in petroleum and reservoir engineering, hydrogeology, geotechnical engineering, packed-bed filtration and porous-materials research. The darcy (D) and its sub-multiples (mD, µD, nD) dominate petroleum-engineering documentation; SI area-equivalent units (m², µm², mm², cm², ft²) appear in geophysics and porous-media research. Intrinsic permeability is a property of the porous medium alone — this category does NOT include hydraulic conductivity (m/s, requires fluid density and viscosity), gas permeability (Klinkenberg slip corrections) or membrane-permeability coefficients, all of which are different physical quantities and require explicit assumptions.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
