About Réaumur and Rankine
Réaumur is a historical scale with water freezing at 0° and boiling at 80°. It is now rare, but survives in some European food and cheese-making traditions.
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 Réaumur and the Rankine are different scales, so the converter applies the exact °Ré → °R formula — handling any offset between them — to give an accurate result every time.
