What Is a Viscosity Converter?
A viscosity converter is an engineering utility that converts a viscosity measurement from one unit into another equivalent unit. Viscosity describes how strongly a fluid resists movement or deformation.
A low-viscosity liquid flows easily, while a high-viscosity liquid flows more slowly. For example, water has a lower viscosity than honey or thick lubricating oil.
Kinematic Viscosity
Kinematic viscosity compares dynamic viscosity with fluid density. Common units include m²/s, mm²/s, stokes and centistokes.

Dynamic vs Kinematic Viscosity
Dynamic viscosity and kinematic viscosity describe related but different fluid properties. Dynamic viscosity represents the force needed to make layers of fluid move past one another.
Kinematic viscosity includes the effect of fluid density. Therefore, a direct conversion between centipoise and centistokes cannot be completed without knowing the density of the fluid.
Important conversion relationships
One centipoise equals one millipascal-second. One poise equals 100 centipoise. One centistoke equals one square millimetre per second, while one stoke equals 100 centistokes.
Frequently Asked Questions
Find answers to common questions about viscosity units and conversions.
A viscosity converter changes a viscosity measurement from one unit to another. This tool supports common dynamic and kinematic viscosity units.
Dynamic viscosity measures a fluid’s resistance to flow when force is applied. Common units include pascal-second, centipoise and poise.
Kinematic viscosity measures dynamic viscosity in relation to the density of a fluid. Common units include centistokes, stokes and square metres per second.
Yes. One centipoise is exactly equal to one millipascal-second.
Yes. One centistoke is exactly equal to one square millimetre per second.
Centipoise and centistokes measure different viscosity types. Fluid density is required to convert dynamic viscosity to kinematic viscosity.
