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.
Réaumur
The Réaumur scale is a temperature scale developed by the French scientist René Antoine Ferchault de Réaumur. On this scale, the freezing point of water is 0 degrees, and the boiling point is 80 degrees under standard atmospheric pressure. While not as widely used as Celsius or Fahrenheit, the Réaumur scale was historically employed in some European countries for scientific and industrial purposes.
