About Temperature Converter
Temperature is the one conversion on this site that is not a simple ratio. Celsius, Fahrenheit and Kelvin do not share a zero point, so their formulas need addition and subtraction as well as multiplication.
To go from Celsius to Fahrenheit, multiply by 9/5 and add 32. To go the other way, subtract 32 and multiply by 5/9. Kelvin shares the size of the Celsius degree but starts at absolute zero, so it is simply Celsius plus 273.15.
