aviation.ch - ICAO Standard Atmosphere

The ICAO Standanrd Atmosphere is a hypothetical model of vertical distribution of atmospheric temperature, pressure, and density that, by international agreement, is taken to be representative of the atmosphere for purposes of pressure altimeter calibrations, aircraft performance calculations and aircraft design.

This calculator will determine the values for pressure, temperature, density and speed of sound for the given altitude.
