Dynamic viscosity

cP to lb/(ft·s) conversion

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

1 cP = 0.000671969 lb/(ft·s)

Formula

To convert centipoise to pound per foot-second, multiply the cP value by 0.000671969. To go the other way, divide by 0.000671969 (or multiply by 1488.164).

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 1 cP is 0.000671969 lb/(ft·s).
