Fahrenheit: Thermometer scale in which the freezing point of water is 32?F and the boiling point of water 212?F.
The Fahrenheit scale is still obstinately in use in the US. This anachronism requires conversion from Centigrade (?C) to Fahrenheit (?F), and vice versa.
One degree ?C = (5/9)(?F - 32).
One degree ?F = (9/5)(?C) + 32.
Named for Gabriel Fahrenheit, a German-Dutch physicist, who devised the scale in 1724. 0?F was the lowest temperature that Fahrenheit could obtain using a mixture of ice and salt.
