As a pilot, you need to know pressure altitude in order to fly safely. Pressure altitude is the height above a standard datum plane, which is determined by the pressure at that height in the atmosphere. To calculate pressure altitude, you need to know the current altimeter setting and the local barometric pressure.

Our pressure altitude calculator takes all the guesswork out of this calculation, providing you with results in seconds. Whether you’re a student pilot or a seasoned professional, our pressure altitude calculator is an indispensable tool for your flight planning needs.
