Calculates the local atmospheric pressure from the elevation, the mean sea-level pressure (MSLP) and the outside air temperature.
The calculation is done with the "barometric formula", which is also used by the weather services.
If no elevation is entered, the calculator assumes sea level.
Then the mean sea-level pressure (MSLP) corresponds to the local atmospheric pressure.
If no mean sea-level pressure (MSLP) is entered, the calculator assumes standard pressure 1013.25 hPa.
If no temperature is entered, the calculator assumes 15°C.
