# Air Pressure at Altitude Calculator

The force applied by the mass of the air particles is called as the air pressure. Air pressure decreases with increase in height. Its because the more air molecules are near the earths surface due to the force of gravity. Calculate the air pressure at altitude using this online simple calculator.

Code to add this calci to your website #### Formula:

P = Po * e((-μgh) / RT) Where, P = Air Pressure at Altitude Po = Sea Level Pressure μ = Molar Mass of Earth Air g = Gravitational Acceleration h = Height R = Air Temperature T = Universal Gas Constant
