Viscosity: The property that represents the internal resistance of a fluid to motion (i.e. fluidity) is called viscosity. There are two ways to write viscosities:
(1) Dynamic viscosity: This is also termed as absolute viscosity. A common unit of dynamic viscosity is poise.
1 poise = 0.1 Pa.s = 0.1 N.s/m2
(2) Kinematic Viscosity: The ratio of dynamic viscosity to density appears frequently and this ratio is given by the name kinematic viscosity. Its unit is Stoke or m2/s (1 stoke = 0.0001 m2 /s).
∴ C.G.S unit of kinematic viscosity is cm2/s.
