How the Temperature Converter works
Enter a temperature and choose the unit you're converting from and to — Celsius, Fahrenheit, or Kelvin. Unlike most units, temperature scales don't share a simple multiplier, so each conversion uses its exact formula rather than a fixed ratio.
Need to convert something other than temperature? The full unit converter also covers length, weight, volume, area, speed, and data storage.
