Viscosity of Air at Different Temperatures
The viscosity of air can vary depending on many factors including temperature. On this page, you can find the dynamic (absolute) and kinematic viscosity of air at different temperature values in both SI (cP) (cSt) and US customary (lbf·s/ft2) (ft/s2) units, taken at 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
