The darcy (or darcy unit) and millidarcy (md or mD) are units of permeability, named after Henry Darcy. They are not SI units, but they are widely used in petroleum engineering and geology. The unit has also been used in biophysics and biomechanics, where the flow of fluids such as blood through … See more Permeability measures the ability of fluids to flow through rock (or other porous media). The darcy is defined using Darcy's law, which can be written as: $${\displaystyle Q={\frac {Ak\,\Delta P}{\mu \,\Delta x}}}$$ See more Converted to SI units, 1 darcy is equivalent to 9.869233×10 m or 0.9869233 µm . This conversion is usually approximated as 1 µm . This is the reciprocal of 1.013250—the conversion factor from atmospheres to bars. Specifically in the … See more The darcy is named after Henry Darcy.
