Centistokes to m²/s (Centistokes to m²/s)
Result
0.000001 m²/s
Formula
m²/s = Centistokes × 0.000001
1 Centistokes = 0.000001 m²/s, and 1 m²/s = 1,000,000 Centistokes.
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 Centistokes × 0.000001 = 0.000001 m²/s
- 10 Centistokes × 0.000001 = 0.00001 m²/s
- 100 Centistokes × 0.000001 = 0.0001 m²/s
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.
