The Delisle scale (abbreviated "De" or "D") is a scale to measure temperature. It was introduced by French astronomer Joseph-Nicolas Delisle in 1732. Delisle used a ther ..more definition+
The Rømer scale (also Roemer) is a temperature scale named after the Danish astronomer Ole Christensen Rømer, who proposed it in 1701. It is based on the freezing point of pure water being 7.5 degrees and the boiling point of water as 60 degrees.
