μ is a more fundamental parameter than the kinematic viscosity (ν)

μ is relatively sensitive to changes in pressure

μ is independent of the rate of strain i.e. the velocity gradient (dv/dy) in a flow field where v=velocity and y = distance from a flow boundary

μ is numerically about 1000 times the kinematic viscosity (ν)

changes by a factor of about 6.3 between temperatures of 0^oC and 100^oC at atmospheric pressure.
