How to convert permeability units

Water-vapor permeability of materials, per unit thickness. Perm-inch uses the 0 °C (conventional) inch of mercury. Every conversion goes through one base unit, the kilogram per pascal second meter, using exact factors, so results don’t drift.

Perm-inches to nanograms per pascal second meter (perm·in to ng/(Pa·s·m))

To convert perm-inches to nanograms per pascal second meter, multiply by 1.453222765. 1 perm-inch = 1.453223 nanograms per pascal second meter.
