Temperature converter: Celsius, Fahrenheit, and Kelvin
The temperature converter transforms between the three most used temperature scales: Celsius (°C), used in most of the world; Fahrenheit (°F), used mainly in the US; and Kelvin (K), the SI base unit used in science and physics.
Temperature conversion formulas
- °C to °F: °F = (°C × 9/5) + 32
- °F to °C: °C = (°F − 32) × 5/9
- °C to K: K = °C + 273.15
- K to °C: °C = K − 273.15
Key reference temperatures
- Absolute zero: 0 K = −273.15 °C = −459.67 °F
- Water freezing: 0 °C = 32 °F
- Room temperature: ~22 °C = 71.6 °F
- Body temperature: 37 °C = 98.6 °F
- Water boiling: 100 °C = 212 °F
- Oven at 350 °F: = 176.7 °C
