A unit for measurement of kinematic viscosity. One centistoke is equal to one hundredth of a stoke, the metric (cgs) unit of kinematic viscosity. The kinematic viscosity in centistokes times the density equals the absolute viscosity in centipoises.
(1) Unit of viscosity (antonym of fluidity). Water has a viscosity of roughly 1 cSt, light cooking oil 100 cSt; (2) A unit of measure of absolute viscosity. (Note: The viscosity to the density of that liquid.)
