How to Use the Temperature Converter
Enter a temperature value and select its current unit (Celsius, Fahrenheit, or Kelvin) — the converter instantly shows the equivalent value in the other two scales, applying the exact conversion formulas automatically.
The Temperature Converter applies the exact formulas for all three scales — here's what to enter.
Entering a value and unit
Enter a temperature and select which scale it's currently in — the tool converts it instantly to the other two scales, removing any need to manually apply the two-step Celsius-Fahrenheit formula or the Kelvin offset.
Converting in either direction
The tool works the same way regardless of which scale you start from — entering a Fahrenheit value converts to Celsius and Kelvin just as readily as starting from Celsius, with no need to remember which formula direction applies.
