Rankine Guide, Meaning , Facts, Information and Description
Rankine is a disused temperature scale named after the Scottish engineer and physicist William John Macquorn Rankine, who proposed it in 1859.The symbol is usually given as °R, but since this may lead to confusion with the Rømer or Réaumur scales, °Ra is to be preferred. Like kelvin, Rankine zero is absolute zero, but Fahrenheit degrees are used. As a result, a difference of 1°Ra is equal to a difference of 1°F, but 0°Ra is -459.67°F.
