Kinematic Viscosity Units Converter

Coversion factor: 1 m²/s = 10000 St

Additional information

Kinematic viscosity is the measure of a fluid’s resistance to flow under the influence of gravity. It is defined as the ratio of dynamic viscosity (absolute viscosity) to the density of the fluid.

The standard unit for kinematic viscosity in the International System of Units (SI) is square meters per second (m²/s). This unit is derived from the ratio of dynamic viscosity measured in pascal-seconds (Pa·s) to the density of the fluid measured in kilograms per cubic meter (kg/m³).

In the US customary system of units, kinematic viscosity values are typically expressed in square foot per second (ft²/s) or square inch per second (in²/s).
