Temperature Conversion Formulas

The exact Celsius, Fahrenheit, and Kelvin conversion formulas used by every SpecWhale temperature converter.

Unlike every other group in this reference library, temperature scales don't convert by multiplying by a single factor -- each pair has its own offset-and-scale formula.

ConversionFormula
Celsius to FahrenheitF = C x 9/5 + 32
Fahrenheit to CelsiusC = (F - 32) x 5/9
Celsius to KelvinK = C + 273.15
Kelvin to CelsiusC = K - 273.15
Fahrenheit to KelvinK = (F - 32) x 5/9 + 273.15
Kelvin to FahrenheitF = (K - 273.15) x 9/5 + 32
