The formulas
- °F → °C: (F − 32) × 5 ÷ 9
- °C → °F: C × 9 ÷ 5 + 32
- °C → K: C + 273.15
- K → °C: K − 273.15
Why three scales
Celsius is the everyday metric standard, Fahrenheit dominates in the US and a few Caribbean countries, and Kelvin is the SI absolute scale used in physics. They share the same step size for Celsius and Kelvin (1 °C = 1 K of change), but offset by 273.15. Fahrenheit's step is 9/5 of a Celsius degree, so its scale stretches across larger numbers.
