Delisle is also the name of a historical temperature scale devised by French astronomer Joseph-Nicolas Delisle in the 18th century. In the Delisle scale, 0 degrees corresponds to the boiling point of water and 100 degrees to the freezing point; the scale increases as temperature decreases. It was used primarily in Russia and some parts of Europe before being superseded by more modern scales.
