1 kg/(Pa·s·m²) = 1.747839234e+10 perm (0°C)
1 perm (0°C) = 5.72135e-11 kg/(Pa·s·m²)
To convert kilogram per pascal second square meter to permeability (0°c), multiply by 1.747839234e+10.
To convert permeability (0°c) to kilogram per pascal second square meter, multiply by 5.72135e-11.
Example: convert 10 kg/(Pa·s·m²) to perm (0°C)
10 × 1.747839234e+10 = 1.747839234e+11 perm (0°C)
Short background on the units used in this conversion.
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.
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.
perm (0°C) = kg/(Pa·s·m²) × 17,478,392,337.4728kg/(Pa·s·m²) = perm (0°C) × 5.72135e-11, using the same exact factors as this converter.Jump to any permeability conversion starting from kilogram per pascal second square meter — including the reverse direction and every other unit in our dataset.
