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.

Réaumur unit in Temperature

The Réaumur scale, established by French scientist René Antoine Ferchault de Réaumur in 1730, sets the freezing point of water at 0 degrees and the boiling point at 80 degrees. This scale was historically important in parts of Europe, particularly in France and Germany, where it was used for various scientific and industrial purposes, such as in the production of cheese and alcohol. Although it has largely been replaced by the Celsius and Fahrenheit scales, the Réaumur scale remains a point of historical interest, especially in studies of early scientific instrumentation and temperature measurement techniques.
