Dynamic viscosity
Convert pascal-second (Pa·s) to centipoise (cP). Dynamic viscosity is a fluid's resistance to shear — the property that sets the Reynolds number and the friction factor.
1 Pa·s = 1000 cP
To convert pascal-second to centipoise, multiply the Pa·s value by 1000. To go the other way, divide by 1000 (or multiply by 0.001).
| Pa·s | cP |
|---|---|
| 1 | 1000 |
| 2 | 2000 |
| 5 | 5000 |
| 10 | 10000 |
| 25 | 25000 |
| 50 | 50000 |
| 100 | 100000 |
| 250 | 250000 |
| 500 | 500000 |
| 1000 | 1000000 |
Liquid viscosities are usually quoted in centipoise (cP); water is about 1 cP at room temperature.
One centipoise equals exactly one millipascal-second, the convenient bridge between the cgs and SI conventions.
Worked example. A dynamic viscosity of 0.001 Pa·s is 1 cP.
Multiply the value in Pa·s by 1000 to get cP. For example, 10 Pa·s = 10000 cP.
1 Pa·s equals 1000 cP.
