Definition of the kinematic viscosity:

Equation 2.10

ν = η/ρ

ν (ny, pronounced: nu or new), with the density ρ [kg/m3], (rho, pronounced: ro).

For the unit of density holds: 1 g/cm3 = 1000 kg/m3

The unit of kinematic viscosity is [mm2/s]; and: 1 mm2/s = 10-6 m2/s

A previously used unit was [St] (stokes); with: 1 St = 100 cSt. This unit was named in honor to the mathematician and physicist George G. Stokes (1819 to 1903) [2.12].

The following holds: 1 cSt (centistokes) = 1 mm2/s.
