Vice Versa: degree celsius to degree réaumur

Degree Réaumur

The degree Réaumur (°r) is a historical temperature scale interval where water freezes at 0°r and boils at 80°r. A Réaumur interval of 1°r equals 1.25 K or 1.25°C. It was used widely in France and Europe in the 18th and 19th centuries for scientific measurements.

Degree Celsius

The degree Celsius (°C) as a temperature interval is equal to one kelvin. While the Celsius scale has an offset from absolute zero, a Celsius interval (difference between two temperatures) is identical in magnitude to a kelvin interval. It is used in everyday science and engineering.
