How to convert ng/ to perms
perm = ng/(Pa⋅s⋅m²) × 0.01740568296Because one perm equals 57.4525 ng/, you can also divide: perm = ng/(Pa⋅s⋅m²) ÷ 57.4525.
A nanogram per pascal second square meter is smaller than a perm: it takes 57.4525 ng/ to make one perm.

About the units
Nanogram per pascal second square meter (ng/(Pa⋅s⋅m²))
The nanogram per pascal second square meter (ng/(Pa⋅s⋅m²)) is a unit of water vapor permeance in the International System of Units (SI). One nanogram per pascal second square meter equals 1×10⁻¹² kg/ (kg/(Pa⋅s⋅m²)).
Perm (perm)
The US perm, one grain of water vapour per hour per square foot per inch of mercury (at 23 °C). One perm equals 5.74525×10⁻¹¹ kg/ (kg/(Pa⋅s⋅m²)).
