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… (More on Poise)
