Calculate Atmospheric Pressure from Elevation
Calculates the local atmospheric pressure based on the current location’s elevation, temperature, and sea-level pressure.
| Air Pressure at Current Location P | hPa |
| = | atm |
The atmospheric pressure values shown on weather maps are calibrated to an elevation of 0 m.
This method cannot be applied at locations higher than the troposphere (approximately 11 km) because the rate of temperature decrease differs at those altitudes.
Calibration to sea-level pressure is calculated using the following altimetry formula.
