Nanograms per pascal second square meter to metric perms
Type a value in ng/(Pa·s·m²) to get it in perm (metric) instantly.
That's 1.74× as open as aluminum foil, while polythene sheet is 3.4× higher. That is a class I vapor barrier: essentially nothing gets through.
What it means
How much vapor gets through?
Permeance belongs to a material of a stated thickness. Permeability — perm-inches — belongs to the material itself, and must be divided by the thickness.
The math
How to convert ng/(Pa·s·m²) to perm (metric)
To convert nanograms per pascal second square meter to metric perms, multiply by 0.0115191.
Example: 1 ng/(Pa·s·m²) × 0.0115191 = 0.0115191 perm (metric).
In the other direction, 1 perm (metric) = 86.8127 ng/(Pa·s·m²).
