Fahrenheit

(F) a temperature scale, devised by the German physicist Gabriel Fahrenheit (1686-1736), that set the freezing point of water at 32º and the boiling point at 212º. Fahrenheit temperatures can be converted to CELSIUS by the equation F = 1.8C + 32.

Fahrenheit is the temperature scale proposed in 1724 by, and named after, the physicist Daniel Gabriel Fahrenheit (1686–1736). Today, the temperature scale has been replaced by the Celsius scale in most countries. It is still in use for non-scientific purposes in the United States and a few other nations, such as Belize.
