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. |
