 | Stokes (st): multiples and submultiples |
 | 1 st = cm2·s-1 = 0.0001 m2·s-1
The SI unit of kinematic viscosity is square meter per second (m2/s), whereas the CGS unit for kinematic viscosity is the stokes , named after Sir George Gabriel Stokes. In U.S. usage, stoke is sometimes used as the singular form. The submultiple centistokes (cSt) is often used instead, 1 cSt = 1 mm2·s-1 = 10-6 m2·s-1. The kinematic viscosity of water at 20 °C is about 1 cSt. |
