Rømer to Delisle Conversion: A Comprehensive Guide

Delve into the fascinating world of historical temperature scales with our guide to converting between Rømer and Delisle. While these scales may seem unfamiliar today, understanding their intricacies offers valuable insights into the evolution of scientific measurement.

Exploring the Rømer Scale

Created by Danish astronomer Ole Rømer in 1701, the Rmer scale is a descending scale where the freezing point of brine (a saltwater solution) is defined as 0°Rø, and the boiling point of water is set at 60°Rø.

Understanding the Delisle Scale

Developed by French astronomer Joseph-Nicolas Delisle in 1732, the Delisle scale is another descending scale. On this scale, the boiling point of water is designated as 0°D, while the freezing point of water is marked at 150°D.

The Rømer to Delisle Conversion Formula

The mathematical relationship between these two scales can be expressed by the following formula:

Delisle (°D) = (7.5 - Rmer (°Rø)) * (25/2)
