*Permeability (electromagnetism), the degree of magnetization of a material in response to a magnetic field
*Permeability (earth sciences), a measure of the ability of a material (such as rocks) to transmit fluids
*Semipermeable membrane, a membrane which will allow certain molecules or ions to pass through it by diffusion
*Permeability (nautical), in ship design, the percentage of empty space in a compartment or tank
