Dynamic viscosity

lb/(ft·s) to Pa·s conversion

Convert pound per foot-second (lb/(ft·s)) to pascal-second (Pa·s). Dynamic viscosity is a fluid's resistance to shear — the property that sets the Reynolds number and the friction factor.

1 lb/(ft·s) = 1.488164 Pa·s

Formula

To convert pound per foot-second to pascal-second, multiply the lb/(ft·s) value by 1.488164. To go the other way, divide by 1.488164 (or multiply by 0.671969).

Used in practice

Liquid viscosities are usually quoted in centipoise (cP); water is about 1 cP at room temperature.

One centipoise equals exactly one millipascal-second, the convenient bridge between the cgs and SI conventions.

Worked example. A dynamic viscosity of 0.000671969 lb/(ft·s) is 0.001 Pa·s.
