The Rømer and Réaumur scales are both historical temperature scales. While less common today, understanding their conversions can be crucial for historical research or scientific data analysis. This blog post will guide you through the Rmer to Réaumur conversion process and provide a handy online calculator.
The Rømer scale, developed by Danish astronomer Ole Rømer in 1701, is a descending scale. On this scale, the freezing point of brine (a mixture of salt and water) is 0°Rø, and the boiling point of water is 60°Rø.
The Réaumur scale, developed by French scientist René Antoine Ferchault de Réaumur in 1730, is also a descending scale. On this scale, the freezing point of water is 0°R, and the boiling point of water is 80°R.
The formula to convert Rømer to Réaumur is:
**Réaumur (°R) = (Rømer (°Rø) - 7.5) * (4/21)**
To make the conversion process easier, we've created a simple online calculator:

Simply enter the temperature in Rømer degrees (°R) into the calculator, and it will instantly display the equivalent temperature in Réaumur degrees (°R).
Let's say you have a temperature of 30°Rø. To convert this to Réaumur:
