Poise quick reference
| Poise | Pascal second | Centipoise | Millipascal second |
|---|---|---|---|
| 1 P | = 0.1 Pa·s | = 100 cP | = 100 mPa·s |
| 10 P | = 1 Pa·s | = 1000 cP | = 1000 mPa·s |
| 100 P | = 10 Pa·s | = 10000 cP | = 10000 mPa·s |
| 1000 P | = 100 Pa·s | = 100000 cP | = 100000 mPa·s |
Where the poise fits
The next smaller dynamic viscosity unit is the millipascal second (mPa·s). 1 P = 100 mPa·s, and 1 mPa·s = 0.01 P.
The next larger dynamic viscosity unit is the pascal second (Pa·s). 1 P = 0.1 Pa·s, and 1 Pa·s = 10 P.
