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:

Dynamic viscosity: This is also termed as absolute viscosity. The unit of dynamic viscosity of a fluid is N.s/m2. A common unit of dynamic viscosity is poise. The dimensions of the coefficient of dynamic viscosity are ML-1T-1

1 poise = 0.1 Pa.s = 0.1 N.s/m2

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).
