Centipoise quick reference
| Centipoise | Pascal second | Pound per foot second | Millipascal second |
|---|---|---|---|
| 1 cP | = 0.001 Pa·s | ≈ 0.0006719689751 lb/(ft·s) | = 1 mPa·s |
| 10 cP | = 0.01 Pa·s | ≈ 0.006719689751 lb/(ft·s) | = 10 mPa·s |
| 100 cP | = 0.1 Pa·s | ≈ 0.06719689751 lb/(ft·s) | = 100 mPa·s |
| 1000 cP | = 1 Pa·s | ≈ 0.6719689751 lb/(ft·s) | = 1000 mPa·s |
Where the centipoise fits
The next larger dynamic viscosity unit is the poise (P). 1 cP = 0.01 P, and 1 P = 100 cP.
