How are Fahrenheit temperatures converted to Celsius?
Celsius is the unit of temperature measurement in the metric system. The easiest way to convert Fahrenheit to Celsius is to subtract 32 from the Fahrenheit reading, divide that number by 9, then multiply the result by 5. To reverse the process, multiply a Celsius reading by 9, divide the answer by 5, then add 32 to the result. According to the U.S. Metric Association, the only other countries other than the USA that have not officially adopted the metric system are Liberia (in western Africa) and Myanmar, in Southeast Asia.
