FAQ
What is the conversion factor from cm² to kD?
1 cm² equals 101325 kD. To convert, multiply the value in square centimetres (permeability) by 101325.
How do I convert 1 cm² to kD?
1 cm² = 101325 kD. For any value, multiply by 101325.
How do I convert kD back to cm²?
Divide by the same factor — or equivalently, multiply by 9.869233e-6. So 1 kD = 9.86923e-6 cm².
When would I need to convert square centimetre (permeability) to kilodarcy?
Permeability conversions between cm² and kD 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).
