Kilogram per Pascal Second Square Meter
kg/(Pa·s·m²)
Definition
The kilogram per pascal second square meter is the SI base unit for permeability, representing the mass flow rate of a fluid through a material per unit pressure gradient and per unit area. It measures how easily a fluid can pass through a porous material under a pressure difference.
History/Origin
The kilogram per pascal second square meter was established as the SI base unit for permeability following the adoption of the International System of Units. It derives from the fundamental relationship between mass flow, pressure gradient, and area in fluid mechanics and porous media studies.
Current Use
Kilogram per pascal second square meter is widely used in scientific research, engineering applications, and industrial processes where precise permeability measurements are required, including petroleum engineering, groundwater studies, and materials science.

Permeability Inches (0°C)
perm·in (0°C)
Definition
The permeability inches at 0°C is a unit of permeability used in the US building industry, representing the vapor transmission rate through a material at 0 degrees Celsius per inch of thickness. It provides a thickness-normalized measure of material permeability.
History/Origin
The permeability inches at 0°C was developed in the US building industry as a practical unit that accounts for material thickness in permeability measurements. It allows for direct comparison of materials with different thicknesses in construction applications.
Current Use
Permeability inches at 0°C is used in US building codes, construction specifications, and material testing where thickness-normalized permeability values are needed for proper material selection and building envelope design.
