How these units are defined
Dynamic viscosity (Pa·s, poise; 1 cP = 1 mPa·s) measures resistance to flow. Kinematic viscosity (m²/s, stokes; 1 cSt = 1 mm²/s) is dynamic viscosity divided by density.
Kinematic Viscosity
| Unit | Equals |
|---|---|
| 1 Stokes | 0.0001 m²/s |
| 1 Centistokes | 0.000001 m²/s |
Dynamic Viscosity
| Unit | Equals |
|---|---|
| 1 Poise | 0.1 Pascal-second |
| 1 Centipoise | 0.001 Pascal-second |
Worked examples
- 1 m²/s = 10,000 Stokes
- 10 m²/s = 100,000 Stokes
- 100 m²/s = 1,000,000 Stokes
Common mistakes
- Kinematic and dynamic viscosity are different quantities: to go from centipoise to centistokes, divide by the fluid's density in g/cm³. For water at 20 °C the two are both about 1.0.
- Motor-oil grades (SAE 5W-30) are classifications, not viscosity units.
