Convert temperatures between Celsius (°C), Fahrenheit (°F) and Kelvin (K). Enter a value and read the result instantly.
The conversion formulas
- °C → °F:
°F = °C × 9/5 + 32 - °F → °C:
°C = (°F − 32) × 5/9 - °C → K:
K = °C + 273.15 - K → °C:
°C = K − 273.15
Handy reference points
- Water freezes: 0 °C = 32 °F = 273.15 K
- Water boils: 100 °C = 212 °F = 373.15 K
- Body temperature: 37 °C = 98.6 °F
- −80 °C freezer: −80 °C = −112 °F = 193.15 K
