Air - Dynamic and Kinematic Viscosity

Online calculator, figures and tables with dynamic (absolute) and kinematic viscosity for air at temperatures ranging -100 to 1600°C (-150 to 2900°F) and at pressures ranging 1 to 10 000 bara (14.5 - 145000 psia) - SI and Imperial Units.

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/m ² , cP, mPa*s, lb _f *s/ft ² and lb _m /(ft*h),
while the kinematic viscosity is given as cSt, m ² /s, and ft ² /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.
