Dynamic viscosity
Convert pascal-second (Pa·s) to poise (P). Dynamic viscosity is a fluid's resistance to shear — the property that sets the Reynolds number and the friction factor.
1 Pa·s = 10 P
To convert pascal-second to poise, multiply the Pa·s value by 10. To go the other way, divide by 10 (or multiply by 0.1).
| Pa·s | P |
|---|---|
| 1 | 10 |
| 2 | 20 |
| 5 | 50 |
| 10 | 100 |
| 25 | 250 |
| 50 | 500 |
| 100 | 1000 |
| 250 | 2500 |
| 500 | 5000 |
| 1000 | 10000 |
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 0.01 P.
Multiply the value in Pa·s by 10 to get P. For example, 10 Pa·s = 100 P.
1 Pa·s equals 10 P.
