Permeability is the property of cellular membranes to allow selectively the diffusion of certain nutrients, ions, molecules or information through them. Typically, there are no permeable membranes in nature but are either selectively permeable or semi permeable which allow the exchange of ions or molecules through them with other molecules or with nature itself. They are present in both plants and animals. Depending on the membrane and the solute itself the permeability of a cellular membrane depends on various factors like the nature of the membrane, cell's operations and the nature of the solute, etc.

Permeability has been commonly symbolised as κ, or k. Permeability is the measure of an ability of the material more commonly of rock or unconsolidated material, to transmit fluids. Permeability is very important in the determination of the flow of the characteristics of hydrocarbons in Oil and in Gas reservoirs; it is also used as groundwater in aquifers

The measurement of permeability needs to be measured by using Darcy's Law or through the estimation uses empirically derived formulas. The common unit for permeability is 'Darcy'. The other units are cm² and the SI m2 . Unconsolidated sands may have permeability's of over 5000 md.
