Permeability has dimensions of area: square meters, square centimeters or square feet.
Permeability can also be measured in darcy. One darcy (or 1 D) is equivalent to the permeability of a medium, through which flow velocity is equal 1 cm/s with a pressure difference of 1 atm over 1 cm and a liquid viscosity equal to 1 centipoise (cP).
