Pressure Altitude Converter
Convert between pressure altitude and atmospheric pressure using the International Standard Atmosphere (ISA) model. Supports feet, meters, hPa, inHg, PSI, and atm.
How to Use Pressure Altitude Converter
The Pressure Altitude Converter transforms between altitude and atmospheric pressure using the International Standard Atmosphere (ISA) barometric formula. Choose your conversion direction: altitude to pressure or pressure to altitude. Enter the value with appropriate units (feet/meters for altitude, hPa/inHg/PSI/atm for pressure) and get the converted result. Based on ISA conditions: sea level pressure 1013.25 hPa, temperature 15°C, lapse rate 6.5°C/1000m. Valid for the troposphere (0–11,000m). Essential for pilots, meteorologists, and aviation enthusiasts.
