# Altitude from atmospheric pressure Calculator

## Calculates the altitude at the present location from the atmospheric pressure and temperature, and sea-level pressure. | ||

The atmospheric pressure observed is adjusted to the equivalent sea level pressure in order to construct the isobaric weather map. If the altitude is more than 11km high above sea level, the hypsometric formula cannot be applied because the temperature lapse rate varies considerably with altitude. |

- Purpose of use

- The altimeter of my aircraft does not take into account the temperature.

Why do you need temperature to compute elevation data ?

Thanks

- If I wantt o use this in altitude calculations for a drone, every time I take it out I have to research the sea level temperature and pressure and adjust accordingly?
