Key Terminology
-
Square millimeter per second (mm²/s)
-
A metric unit of kinematic viscosity equal to 1×10⁻⁶ m²/s and equivalent to 1 centistoke.
-
Square inch per second [in²/s]
-
An imperial unit of kinematic viscosity representing one square inch of area moved per second, used as the US customary counterpart to the stokes.
-
Kinematic viscosity
-
A measure of a fluid's internal resistance to flow under gravity, defined as the ratio of dynamic viscosity to density.
