How to use Viscosity Converter

Use the dynamic panel for Pa·s/cP/poise and the kinematic panel for m²/s/cSt/stokes. Each converts within its own base independently.

Frequently asked questions

How many centipoise in a pascal-second?

1 Pa·s equals 1000 cP; water at 20°C is about 1 cP or 0.001 Pa·s.

What is the difference between dynamic and kinematic viscosity?

Dynamic (Pa·s) measures shear resistance; kinematic (m²/s) is dynamic divided by density.

How does cSt relate to m²/s?

1 centistokes equals 10⁻⁶ m²/s, the common unit for oil viscosity grades.
