## Atmospheric pressure at altitude formula

This tool calculates the atmospheric pressure based on altitude and air temperature using the following formula:

`P = P_0*e^(-(mu*g*h)/(R*T))`

`P`: Air pressure at elevation h

`P_0`: Air pressure at sea level

`mu`: Constant, molar mass average of air: M = 0.0289644 kg/mol.

g: Earth gravity constant, g = 9.80665 m/s2

h: Altitude in meter

R: Ideal gas constant R = 8.31432 J/k.mol

T: Air temperature in Kelvin at altitude h
