›› Definition: Rankine

Rankine is a thermodynamic (absolute) temperature scale named after the Scottish engineer and physicist William John Macquorn Rankine, who proposed it in 1859.

The symbol is R (or Ra if necessary to distinguish it from the Rmer and Raumur scales). As with the Kelvin scale (symbol: K), zero on the Rankine scale is absolute zero. The Rankine scale differs from the Kelvin scale in that it uses smaller, degree Fahrenheit-size increments rather than degree Celsius-size increments. A temperature of 459.67 R is precisely equal to and 0 F.

Many engineering fields in the U.S. measure thermodynamic temperature using the Rankine scale. However, throughout the scientific world where measurements are made in SI units, thermodynamic temperature is measured in kelvins.

›› Definition: Celsius

The degree Celsius (C) is a unit of temperature named after the Swedish astronomer Anders Celsius (17011744), who first proposed a similar system in 1742. The Celsius temperature scale was designed so that the freezing point of water is 0 degrees, and the boiling point is 100 degrees at standard atmospheric pressure.
