Rømer to Réaumur Converter

About Rømer (°Rø) and Réaumur (°Ré) Units

The Rømer scale (°Rø) is developed by the Danish astronomer Ole Rømer in 1701. In this system, water freezes at 7.5°Rø and boils at 60°Rø. Rømer created this scale while studying the freezing and boiling points of water for practical scientific measurements. It is no longer used in modern temperature measurements but remains important in historical studies. Réaumur (°Re) is a temperature scale named after the French scientist René Antoine Ferchault de Réaumur. In this scale, water freezes at 0°Re and boils at 80°Re. It was historically used in Europe for scientific work, brewing, and some industrial processes. Although it is largely replaced by Celsius today, Réaumur is still referenced in historical recipes, old scientific texts, and specialty brewing measurements.
