The poise (P; IPA: [pwaz]) is the unit of dynamic viscosity in the centimetre gram second system of units. It is named after Jean Louis Marie Poiseuille.
- 1 P = 1 g·cm−1·s−1
The analogous unit in the International System of Units is the pascal second (Pa·s):
- 1 Pa·s = 1 kg·m−1·s−1 = 10 P
The poise is often used with the prefix centi-; a centipoise is one millipascal second (mPa·s) in SI units.
Centipoise is often abbreviated to cP or cps.
Water has a viscosity of 0.0089 poise at 25 °C, or 1 centipoise at 20 °C.
Poise also refers to a person’s composure, assurance of manner, and confidence in handling situations. See Wiktionary:poise.
