Poise (P)
The poise (P) is the CGS unit of dynamic viscosity, exactly 0.1 Pa·s. It is named after Jean Léonard Marie Poiseuille.
Symbol: P
Quantity: dynamic (absolute) viscosity
SI relation: 1 P = 0.1 Pa·s (exact)
Derivation: 1 P = 1 dyn·s/cm² = 0.1 Pa·s
Exact: yes, by definition
Typical uses
- Older physics and rheology literature
- Glass and polymer melt viscosities
Convert poise to other units
| Conversion | 1 P equals | Reverse |
|---|---|---|
| poise to pascal-second | 0.1 Pa·s | pascal-second to poise |
| poise to centipoise | 100 cP | centipoise to poise |
| poise to millipascal-second | 100 mPa·s | millipascal-second to poise |
| poise to pound-force second per square foot | 0.002088543423 lbf·s/ft² | pound-force second per square foot to poise |
| poise to pound per foot-second | 0.06719689751 lb/(ft·s) | pound per foot-second to poise |
