How to convert Celsius to Fahrenheit
The US National Institute of Standards and Technology gives the conversion as °C = (°F − 32) ÷ 1.8. So to go from °C to °F, multiply by 1.8, then add 32. For example, 250°C is 482°F. See NIST's table.
The two scales meet at −40, where −40°C and −40°F are the same temperature.
