Rankine : Rankine is a thermodynamic temperature scale named after the Glasgow University engineer and physicist William John Macquorn Rankine. The symbol for degrees Rankine is °R (or °Ra). In Rankine scale (°R) zero is absolute zero.
Reaumur : The Réaumur scale, also known as the "octogesimal division", is a temperature scale in which the freezing and boiling points of water are set to 0 and 80 degrees respectively. The scale is named after René Antoine Ferchault de Réaumur. Its symbol are °Ré, °Re and °R.
