Air - Dynamic and Kinematic Viscosity
Online calculator, figures and tables showing dynamic (absolute) and kinematic viscosity of air at temperatures ranging from -100 to 1600°C (-150 to 2900°F) at pressure ranging from 1 to 10 000 bara (14.5 - 145000 psia) - SI and Imperial Units
The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress.
For further definitions, go to Absolute (dynamic) and kinematic viscosity. Absolute or dynamic viscosity is used to calculate Reynold's Number to determine if a fluid flow is laminar, transient or turbulent.
Tabulated values and viscosity units conversion are given below the figures.
Online Air Viscosity Calculator
The calculator below can be used to calculate air dynamic or kinematic viscosity at given temperatures and atmospheric pressure.
The output dynamic viscosity is given as Pa*s, N*s/m2, cP, mPa*s, lbf*s/ft2 and lbm/(ft*h),
while the kinematic viscosity is given as cSt, m2/s, and ft2/s
Note! Temperature must be within the ranges -100 - 1600 °C, -150 - 2900 °F, 175 - 1900 K and 310-3400 °R to get valid values.
