Stokes to Centistokes (Stokes to Centistokes)
Result
100 Centistokes
Formula
Centistokes = Stokes × 100
1 Stokes = 100 Centistokes, and 1 Centistokes = 0.01 Stokes.
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.
Worked examples
- 1 Stokes × 100 = 100 Centistokes
- 10 Stokes × 100 = 1,000 Centistokes
- 100 Stokes × 100 = 10,000 Centistokes
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.
