About Kelvin and Fahrenheit
The kelvin is the SI base unit of temperature, starting at absolute zero (0 K = −273.15 °C). It is used in science and engineering, where an absolute scale matters.
Fahrenheit is the temperature scale used mainly in the United States, with water freezing at 32° and boiling at 212°. It is used for US weather forecasts, ovens and thermostats.
The Kelvin and the Fahrenheit are different scales, so the converter applies the exact K → °F formula — handling any offset between them — to give an accurate result every time.
