Rankine

The Rankine scale is an absolute temperature scale named after the Scottish engineer and physicist William John Macquorn Rankine. Similar to the Kelvin scale, the Rankine scale starts at absolute zero, with each degree Rankine equal to one degree Fahrenheit. This scale is primarily used in thermodynamics and engineering, particularly in the United States. The freezing point of water on the Rankine scale is 491.67 °R, and the boiling point is 671.67 °R.

Delisle

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.
