is the unit of kinematic viscosity in the centimeter-gram-second system. The abbreviation for stoke is symbolized by St (formerly S). Fluid with a dynamic viscosity of 1 poise and a density of 1 gram per cubic centimeter has a kinematic viscosity of 1 stokes  in SI units.

1 stokes = 1 centimeter squared per second:

Note: The dimensions of the stokes in SI base units are centimeter squared per second.
