About Kelvin and Réaumur
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.
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.
The Kelvin and the Réaumur are different scales, so the converter applies the exact K → °Ré formula — handling any offset between them — to give an accurate result every time.
