This temperature converter switches instantly between Celsius, Fahrenheit, and Kelvin.
| Conversion | Formula |
|---|---|
| Celsius → Fahrenheit | °F = °C × 9/5 + 32 |
| Fahrenheit → Celsius | °C = (°F − 32) × 5/9 |
| Celsius → Kelvin | K = °C + 273.15 |
Handy reference points: water freezes at 0 °C (32 °F) and boils at 100 °C (212 °F); normal body temperature is about 37 °C (98.6 °F).
Multiply by 9/5 and add 32. For example, 20 °C = 20 × 9/5 + 32 = 68 °F.
About 37.8 °C, just above normal body temperature.
Absolute zero is 0 Kelvin, equal to −273.15 °C, the lowest possible temperature.
