Pressure Lapse Rate
To calculate the exact pressure lapse rate use this formula: PLR = 96 ( T in kelvin) / local pressure (in hPa). For example at 15°C and ISA QNH: 96 (15+273) / 1013,25 = 27,3 ft/hPa.

Lapse Rate: The rate at which temperature decreases with height. The average lapse rate in the troposphere is 3°F per 1,000ft, but the actual rate varies a good deal between the two extreme conditions of dry and saturated air.
ADIABATIC LAPSE RATE - The rate at which ascending air cools and descending air warms, given no heat is added or taken away. The rate for dry air is based on 5.
