FAQ
What is the conversion factor from kD to D?
1 kD equals 1000 D. To convert, multiply the value in kilodarcy by 1000.
How do I convert 1 kD to D?
1 kD = 1000 D. For any value, multiply by 1000.
How do I convert D back to kD?
Divide by the same factor — or equivalently, multiply by 0.001. So 1 D = 0.001 kD.
When would I need to convert kilodarcy to darcy?
Permeability conversions between kD and D 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).
