Poise

Poise

[poiz]
The poise (symbol P; ) 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 metric prefix centi-. A centipoise is one millipascal-second (mPa·s) in SI units. (1 cP = 10-2P = 10-3 Pa·s) Centipoise is properly abbreviated cP, but the alternate abbreviations cps and cPs are also commonly seen.

Water has a viscosity of 0.0089 poise at 25 °C, or 1 centipoise at 20 °C.
