- centistokes
- (cSt)a common metric unit of kinematic viscosity equal to 0.01 stokes or 1 mm2/s. The viscosity of lubricating oils and many other liquids is frequently stated in centistokes. Although the centistokes is not an SI unit it is likely to remain in use, since it provides a convenient and traditional name for an SI-appropriate quantity (1 mm2/s). The older symbol cS should not be used for this unit, since S is now the symbol for the siemens.
