Convert Fahrenheit To Celsius
|
This measurement conversion is based on a simple rule: 1 ℉ = -17.22222 ℃ 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 Today, the temperature scale has been replaced by the Celsius scale in most countries.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 in few nations, such as United States and Belize.
Celsius (known until 1948 as centigrade) is a temperature scale that is named after the Swedish astronomer Anders Celsius (1701-1744), who developed a similar temperature scale two years before his death. The degree Celsius can refer to a specific temperature on the Celsius scale as well as a unit to indicate a temperature interval (a difference between two temperatures or an uncertainty).
