Accurate conversions across all major temperature scales.
Converting temperatures is simple once you know the formulas.
| Conversion | Formula |
|---|---|
| Celsius to Fahrenheit | (°C × 9/5) + 32 = °F |
| Fahrenheit to Celsius | (°F − 32) × 5/9 = °C |
| Celsius to Kelvin | °C + 273.15 = K |
| Kelvin to Celsius | K − 273.15 = °C |
Also known as Centigrade, the Celsius scale is defined by zero being the freezing point of water and 100 being the boiling point (at standard atmospheric pressure).
It is the standard unit used in almost every country in the world, with the notable exception of the United States.
The Fahrenheit scale freezes water at 32 degrees and boils it at 212 degrees. The interval between these two points is exactly 180 degrees.
It is primarily used in the United States, Bahamas, Cayman Islands, and Liberia.
-40 degrees.
Kelvin is an absolute scale, meaning it starts at absolute zero (the point where all thermal motion ceases). This makes calculations in thermodynamics much simpler.
