Rømer to Réaumur Conversion

Understanding Rømer

Developed by Danish astronomer Ole Rømer in 1701, the Rømer scale is a historical temperature scale where the freezing point of brine (a mixture of salt and water) is set at 0°Rø, and the boiling point of water at 60°Rø.

Understanding Réaumur

Created by French scientist René Antoine Ferchault de Réaumur in 1730, the Réaumur scale is another historical temperature scale. On this scale, water freezes at 0°R and boils at 80°R.

The Conversion Formula

The mathematical magic behind the conversion is captured in this formula:

**Raumur (°R) = (Rømer (°Rø) - 7.5) * (16/21)**
