How it works
The formula behind this calculator.
F = C × 9/5 + 32; K = C + 273.15
- C, F, K
- Celsius, Fahrenheit, Kelvin
Celsius and Fahrenheit are offset scales (different zero points). Kelvin is the absolute scale used in science.
Example: 0°C = 32°F = 273.15 K (water freezing); 100°C = 212°F = 373.15 K (boiling)
Ref: International Temperature Scale of 1990 (ITS-90)
Tips
- 💡 F to C: (F − 32) × 5/9. C to F: (C × 9/5) + 32.
- 💡 Absolute zero is −273.15 °C, −459.67 °F, 0 K.
