How is pressure altitude calculated
WebWhen the pressure or density ratio is known, the altitude to which they correspond can be determined. For instance, if the pressure ratio (δ) is known, the altitude to which it corresponds (called pressure altitude) can be calculated. WebWe can determine pressure height by either: reading the altimeter with 1013 set in the sub-scale; or by using the difference between QNH and 1013 to convert altitude to pressure height. If actual sea level pressure differs from the standard atmosphere of 1013 hPa, then a simple diagram will help us with any calculations of pressure height.

WebPressure to height conversions in altimetry are based on ISA. Independent of temperature, the conversion is 27 ft/hPa in the lower atmosphere (near ground), or 27 ft between each hPa of isobaric surfaces. In non-ISA conditions, altimeter readout may be significantly different than the true altitude of said altimeter.
