Temperature Choose the actual unit of temperature: While the kinematic viscosity is given as cSt, m 2 /s, and ft 2 /s The output dynamic viscosity is given as Pa*s, N*s/m 2, cP, mPa*s, lb f *s/ft 2 and lb m /(ft*h),

The calculator below can be used to calculate air dynamic or kinematic viscosity at given temperatures and atmospheric pressure. Tabulated values and viscosity units conversion are given below the figures. Absolute or dynamic viscosity is used to calculate Reynold's Number to determine if a fluid flow is laminar, transient or turbulent. įor further definitions, go to Absolute (dynamic) and kinematic viscosity. The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress.
