Question

What is the SI Unit of the viscosity coefficient?

Answer 1

The SI unit of kinematic viscosity is m2/s, whereas the cgs unit for kinematic viscosity is the stokes (St), named after Sir George Gabriel Stokes. It is sometimes expressed in terms of centistokes (cSt).

Answer 2

It is commonly expressed, particularly in ASTM standards, as centipoise (cP) since the latter is equal to the SI multiple millipascal seconds (mPa. s). The SI unit of kinematic viscosity is m2/s, whereas the cgs unit for kinematic viscosity is the stokes (St), named after Sir George Gabriel Stokes.
