About Kelvin and Rankine
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.
Rankine is an absolute temperature scale that uses Fahrenheit-sized degrees, starting at absolute zero. It appears in some US engineering and thermodynamics work.
The Kelvin and the Rankine are different scales, so the converter applies the exact K → °R formula — handling any offset between them — to give an accurate result every time.
