Fahrenheit scale

Abbreviation: F.
A temperature scale with the freezing point of water at 32° and the boiling point at 212°. See: table; Celsius ¹scale; Kelvin ¹scale * To convert a Fahrenheit temperature to degrees Celsius, subtract 32 and multiply by 5/9. To convert a Celsius temperature to degrees Fahrenheit, multiply by 9/5 and add 32.
