KILOGRAM PER PASCAL SECOND SQUARE METER

1 kg/(Pa·s·m²) = 17,478,392,337.4728 perm (0°C)

kilogram per pascal second square meter (kg/(Pa·s·m²)) → permeability (0°c) (perm (0°C)) permeability (0°c) (perm (0°C)) → kilogram per pascal second square meter (kg/(Pa·s·m²))

PERMEABILITY (0°C)

1 perm (0°C) = 0.9958400418 perm (23°C)

permeability (0°c) (perm (0°C)) → permeability (23°c) (perm (23°C)) permeability (23°c) (perm (23°C)) → permeability (0°c) (perm (0°C))

PERMEABILITY (23°C)

1 perm (23°C) = 1.0041773358 perm (0°C)

permeability (23°c) (perm (23°C)) → permeability (0°c) (perm (0°C)) permeability (0°c) (perm (0°C)) → permeability (23°c) (perm (23°C))

PERMEABILITY INCHES (0°C)

1 perm in (0°C) = 1.45322e-12 kg/(Pa·s·m²)

permeability inches (0°c) (perm in (0°C)) → kilogram per pascal second square meter (kg/(Pa·s·m²)) kilogram per pascal second square meter (kg/(Pa·s·m²)) → permeability inches (0°c) (perm in (0°C))

PERMEABILITY INCHES (23°C)

1 perm in (23°C) = 1.45929e-12 kg/(Pa·s·m²)

permeability inches (23°c) (perm in (23°C)) → kilogram per pascal second square meter (kg/(Pa·s·m²)) kilogram per pascal second square meter (kg/(Pa·s·m²)) → permeability inches (23°c) (perm in (23°C))
