What is the standard dry adiabatic lapse rate in degrees Fahrenheit per 1000 feet?

Dry adiabatic lapse rate describes how quickly a rising dry air parcel cools as it expands without exchanging heat with its surroundings. For dry air, this rate is about 9.8°C per 1,000 meters. Converting to Fahrenheit per 1,000 feet: 9.8°C per 3,281 ft equals roughly 2.99°C per 1,000 ft, which is about 5.4°F per 1,000 ft. So the standard dry adiabatic lapse rate in °F per 1,000 ft is approximately 5.4°F. (For example, rising 3,000 ft cools the parcel by about 16.2°F.)
