History & Background
The unit "Stokes" honors British physicist George Stokes for his foundational contributions to fluid mechanics. "Saybolt Seconds" was a practical method invented in the late 19th century US.
Conversion Details
Kinematic viscosity is the ratio of dynamic viscosity to fluid density at the same temperature. The SI unit is Stokes (St).
Common conversions: 1 St = 100 cSt.
