Convert between Celsius (°C), Fahrenheit (°F) and Kelvin (K). Handy for weather, cooking and science. Enter a value, choose units — instant results.
Unit conversions
- °F = (°C × 9/5) + 32
- °C = (°F − 32) × 5/9
- K = °C + 273.15
- °C = K − 273.15
Common examples
- Example: 20 °C = 68 °F
- Example: 0 °C = 273.15 K
- Example: 100 °F ≈ 37.78 °C
Common pitfalls
- Kelvin uses K (no degree sign)
- Rounding: cooking vs science needs
- 1 °C = 1.8 °F step size
