The poise (symbol P; / p ɔɪ z, p w ɑː z /) is the unit of dynamic viscosity (absolute viscosity) in the centimetre–gram–second system of units (CGS). [1] It is named after Jean Léonard Marie Poiseuille (see Hagen–Poiseuille equation). The centipoise (1 cP = 0.01 P) is more commonly used than the poise itself.
For dynamic viscosity, the SI unit is Pascal-second. In engineering, the unit is usually Poise or centiPoise, with 1 Poise = 0.1 Pascal-second, and 1 centiPoise = 0.01 Poise. For kinematic viscosity, the SI unit is m^2/s. In engineering, the unit is usually Stoke or centiStoke, with 1 Stoke = 0.0001 m^2/s, and 1 centiStoke = 0.01 Stoke.
The CGS unit is the poise (P, or g·cm −1 ·s −1 = 0.1 Pa·s), [28] named after Jean Léonard Marie Poiseuille. It is commonly expressed, particularly in ASTM standards, as centipoise (cP). The centipoise is convenient because the viscosity of water at 20 °C is about 1 cP, and one centipoise is equal to the SI millipascal second (mPa·s).

Gracefulness, or being graceful, is the physical characteristic of displaying "pretty agility", in the form of elegant movement, poise, or balance. The etymological root of grace is the Latin word gratia from gratus, meaning pleasing. [1] Gracefulness has been described by reference to its being aesthetically pleasing. For example:

By definition, 1 reyn = 1 lb f s in −2.. It follows that the relation between the reyn and the poise is approximately . 1 reyn = 6.89476 × 10 4 P.. In SI units, viscosity is expressed in newton-seconds per square meter, or equivalently in pascal-seconds.
