The Delisle scale, proposed by the French astronomer Joseph-Nicolas Delisle, is a temperature scale where the freezing point of water is 150 degrees and the boiling point is 0 degrees under standard atmospheric pressure. The Delisle scale is unique in that its values decrease as temperature increases, making it less common in contemporary usage compared to other temperature scales.


The Kelvin scale is an absolute temperature scale named after the Scottish physicist William Thomson, 1st Baron Kelvin. It is commonly used in scientific and engineering applications where an absolute temperature reference is required. The Kelvin scale starts at absolute zero, the point at which all molecular motion ceases. The freezing point of water on the Kelvin scale is 273.15 K, and the boiling point is 373.15 K.
