Pressure Altitude Calculator

An online Aviation calculator to calculate the Pressure altitude. It is the height above a standard datum plane (SDP). It is the theoretical level where the weight of the atmosphere is 29.92 'Hg', which is measured by a barometer. Pressure Altitude Calculator is designed to find the value for a calculated pressure altitude, based on the specific gravity value. Specific gravity is the density of an object which is equal to its mass divided by its volume.
