Converting from Réaumur (°Ré) to Rømer (°Rø)

What is Réaumur (°Ré)

Réaumur (°Ré) is a temperature scale where the freezing point of water is 0°Ré and the boiling point is 80°Ré. It was created by René Antoine Ferchault de Réaumur in the early 18th century.

What is Rømer (°Rø)

Rømer (°Rø) is another historical temperature scale developed by Ole Christensen Rømer, where the freezing point of water is 7.5°Rø and the boiling point is 60°Rø. It was commonly used in Northern Europe during the 17th and 18th centuries.

Conversion Formulas

The conversion formulas between Réaumur (°Ré) and Rømer (°Rø) are as follows:

°Rø=45​×°Ré+7.5

°Ré=54​×(°Rø−7.5)

Examples

1. Converting 15°Ré to °Rø

°Rø=45​×15+7.5=17.34375(°Rø)

2. Converting 6°Rø to °Ré

°Ré=54​×(6−7.5)=−2.285714(°Ré)

3. Converting 13°Ré to °Rø

°Rø=45​×13+7.5=16.03125(°Rø)

4. Converting 15°Rø to °Ré

°Ré=54​×(15−7.5)=11.42857(°Ré)

Through these conversion formulas, you can easily switch between Réaumur (°Ré) and Rømer (°Rø) temperature scales.
