  1. Find the conversion factor from Perm inch (23 °C) to Nanogram per pascal second meter

    1 perm·in (23 °C) = 1.45929e-12 kg/(Pa·s·m) · 1 ng/(Pa·s·m) = 1e-12 kg/(Pa·s·m)

    factor = 1.45929e-12 ÷ 1e-12 = 1.45929 ng/(Pa·s·m) per perm·in (23 °C)

  2. Multiply by the factor: perm·in (23 °C) cancels, leaving ng/(Pa·s·m)

    ng/(Pa·s·m) = perm·in (23 °C) × (ng/(Pa·s·m) per perm·in (23 °C))

    1 perm·in (23 °C) × 1.45929 ng/(Pa·s·m) per perm·in (23 °C) = 1.45929 ng/(Pa·s·m)

How it works

1 perm·in (23 °C) = 1.45929 ng/(Pa·s·m), so ng/(Pa·s·m) = perm·in (23 °C) × 1.45929

Permeability is per unit thickness. Permeance (perms, without the inch) describes a specific layer.

Questions

How do I convert perm inch (23 °C) to nanogram per pascal second meter?
Multiply by 1.45929. For example, 10 perm·in (23 °C) = 14.5929 ng/(Pa·s·m).
Which units does the permeability (water vapor) converter support?
Kilogram per pascal second meter (kg/(Pa·s·m)), Nanogram per pascal second meter (ng/(Pa·s·m)), Perm inch (0 °C) (perm·in), Perm inch (23 °C) (perm·in (23 °C)).
Anything to watch out for?
Permeability is per unit thickness. Permeance (perms, without the inch) describes a specific layer.
