You can obtain the kinematic viscosity of air by dividing dynamic viscosity by the density ρρ: ν=μρν=ρμ In the SI system, the unit of kinematic viscosity is m2/s, but other commonly used units are Stokes (St): 1 St = 10-4 m2/s = 1 cm2/s. Since 1 Stoke is a large ...
The unit of viscosity, accordingly, is newton-second per square metre, which is usually expressed as pascal-second in SI units. The viscosity of liquids decreases rapidly with an increase in temperature, and the viscosity of gases increases with an increase in temperature. Thus, upon heating, ...
Using the SI units of viscosity, shear stress was in N/m2and shear rate was in (m/s)/m = 1/s, so dynamic viscosity has units of Ns/m2(newton-seconds per meter squared) or Pa s (pascal-seconds). However, the most common unit of viscosity is the dyne-second per square centimeter ...

Units of viscosity Dynamic viscosity Poise (symbol: P) Named after the French physician Jean Louis Marie Poiseuille (1799– 1869), this is the cgs unit of viscosity, equivalent to dyne-second per square centimetre. It is the viscosity of a fluid in which a tangential force of 1 dyne per ...
