Delisle to Rømer Converter

About Delisle (°D) and Rømer (°Rø) Units

The Delisle scale (°De), created in 1732 by French astronomer Joseph-Nicolas Delisle, is a historical temperature system. Unlike modern scales, it sets the boiling point of water at 0°De and the freezing point at 150°De. This scale was mainly used in Russia and parts of Europe for early meteorological observations and scientific measurements. Although no longer used today, Delisle remains of interest for historical studies and temperature conversions. 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.
