About Rankine and Celsius
Rankine is an absolute temperature scale that uses Fahrenheit-sized degrees, starting at absolute zero. It appears in some US engineering and thermodynamics work.
Celsius is the everyday metric temperature scale, with water freezing at 0° and boiling at 100° at sea level. It is used for weather, cooking and body temperature almost everywhere outside the US.
The Rankine and the Celsius are different scales, so the converter applies the exact °R → °C formula — handling any offset between them — to give an accurate result every time.
