Permeability (0°C) (perm (0°C))
Perm (0°C) equals 5.72135×10⁻¹¹ kg/(Pa·s·m²) — the US building-science perm unit referenced at 0°C.
Perm at 0°C rates vapor permeance of house wraps, sheathing, and insulation in US construction codes.

How to convert
Exact conversion factors in both directions, plus a worked example.
1 perm (0°C) = 5.72135e-11 kg/(Pa·s·m²)
1 kg/(Pa·s·m²) = 1.747839234e+10 perm (0°C)
To convert permeability (0°c) to kilogram per pascal second square meter, multiply by 5.72135e-11.
To convert kilogram per pascal second square meter to permeability (0°c), multiply by 1.747839234e+10.
Example: convert 10 perm (0°C) to kg/(Pa·s·m²)
10 × 5.72135e-11 = 5.72135e-10 kg/(Pa·s·m²)
About these units
Short background on the units used in this conversion.
Kilogram per Pascal Second Square Meter (kg/(Pa·s·m²))
The kilogram per pascal second square meter (kg/(Pa·s·m²)) is the SI base for vapor permeability through materials.
SI permeability quantifies how readily water vapor passes through membranes, films, and building assemblies.
Frequently asked questions
How many kilograms per pascal second square meter are in one permeability (0°c)?
One permeability (0°c) equals 0.0000000000572135 kilograms per pascal second square meter. Multiply your perm (0°C) units value by 0.0000000000572135 to convert to kilograms per pascal second square meter.
What is the conversion formula?
kg/(Pa·s·m²) = perm (0°C) × 0.0000000000572135The reverse is
