Pressure & Temperature At Altitude

This calculator provides values of the pressure and temperature at a specific altitude. These values are then used to calculate a value of 'Equivalent Pressure'. This is sometimes used in testing where the test object performance is only likely to be influenced by relative air density (not the case for test objects where changes in permittivity / conductivity will impact the electric field). The values are based on the ICAO standard atmosphere.

The calculator can be used for altitudes between 0m and 20,000m.
