Poise 泊 (单位)
The poise (symbol P, ) is the unit of dynamic viscosity in the centimetre gram second system of units. It is named after Jean Léonard Marie Poiseuille.
The analogous unit in the International System of Units is the pascal second (Pa·s):
The poise is often used with the metric prefix centi- because the viscosity of water at 20C is almost exactly 1 centipoise. A centipoise is one one-hundredth of a poise, and one millipascal-second (mPa·s) in SI units. (1 cP = 10 P = 10 Pa·s = 1 mPa·s)
