How to convert Fahrenheit to Celsius
The US National Institute of Standards and Technology gives the conversion as °C = (°F − 32) ÷ 1.8. So to go from °F to °C, take away 32, then divide by 1.8. For example, 72°F is 2222°C.. See NIST's table.
The two scales meet at −40, where −40°C and −40°F are the same temperature.
