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 (0°C)
perm (0°C)
Definition
The permeability at 0°C is a traditional unit of permeability used in building materials and textiles, representing the vapor transmission rate through a material at 0 degrees Celsius. It is commonly used in the construction industry for measuring moisture vapor transmission.
History/Origin
The permeability at 0°C was developed in the building materials industry as a practical unit for measuring moisture vapor transmission through construction materials. It became standardized for comparing the breathability of different building materials and textiles.
Current Use
Permeability at 0°C is extensively used in the construction industry, textile manufacturing, and building materials testing where moisture control and vapor transmission are critical for material performance and building envelope design.
