What is the formula to convert from Rømer to Delisle?

Temperature_(Delisle) = (100 - (Temperature_(Rømer) - 7.5) × 40 / 21 ) × 3 / 2

Rømer unit in Temperature

The Rømer scale, proposed by Danish astronomer Ole Rømer in 1701, was an early attempt to standardize temperature measurement. On this scale, the freezing point of water is set at 7.5 degrees, and the boiling point is 60 degrees. The Rømer scale was one of the first to be based on the properties of water, and it laid the foundation for later developments in temperature measurement, including the Celsius scale. Although it has been largely superseded, the Rømer scale remains of historical significance, particularly in the history of science and the development of meteorology and thermometry in Denmark.

Delisle unit in Temperature

The Delisle scale, introduced by French astronomer Joseph-Nicolas Delisle in 1732, is unique in that its temperature values decrease as the temperature increases, making it an inverted temperature scale. Water freezes at 150 degrees and boils at 0 degrees on this scale. The Delisle scale was used primarily in Russia during the 18th century, particularly in astronomy and other scientific fields. Though it is no longer in common use, the Delisle scale is noted for its historical significance and its unique approach to temperature measurement, offering insights into the development of scientific thought in the early modern period.
