What is a temperature converter?
A temperature converter changes a reading between the Celsius (°C), Fahrenheit (°F) and Kelvin (K) scales. All three measure the same thing but start at different points and use different step sizes.
How it works
Unlike most conversions, temperature uses formulas, not a single ratio, because the scales have different zero points. Celsius to Fahrenheit is °F = °C × 9/5 + 32. Celsius to Kelvin is K = °C + 273.15. The tool applies the right formula for the scales you pick.

How to use
Enter a temperature, choose the unit you have it in, and the unit you want it in. The converted value appears immediately.
The calculator uses the standard formulas: °F = °C × 9/5 + 32 and K = °C + 273.15. Conversions always pass through Celsius, so going from °F to K (or back) is exact.
