How to use this converter
Choose your starting and destination units, then enter a value. Results update as you type. You can swap the direction and choose the displayed precision.
Example: Kilograms per pascal second square meter to US perm (0 °C)
value × 17478392337.5 = result
Here the starting unit is Kilograms per pascal second square meter (kg/(Pa·s·m²)) and the result is in US perm (0 °C) (perm 0°C). The calculator uses the catalog’s full factors before rounding the displayed result.
Worked examples
- 1 kg/(Pa·s·m²) ≈ 17,478,392,337.4728 perm 0°C
- 10 kg/(Pa·s·m²) ≈ 174,783,923,374.728 perm 0°C
- 100 kg/(Pa·s·m²) ≈ 1.74783923e+12 perm 0°C
Available permeability options
Kilograms per pascal second square meter (kg/(Pa·s·m²)) · US perm (0 °C) (perm 0°C) · US perm (23 °C) (perm 23°C) · Perm-inch (0 °C) (perm·in 0°C) · Perm-inch (23 °C) (perm·in 23°C)
Unit conventions
This category follows the reference’s water-vapor permeance conventions, not intrinsic permeability in darcies.
Frequently asked questions
Why can displayed results differ slightly?
Numeric results are rounded for display. Increase the precision setting to see more digits. Different unit conventions can also produce different results; check the complete unit label.
Can I convert in the opposite direction?
Use the swap control to reverse the selected units or bases.
