What are Rankine and Reaumur

The Rankine scale (°Ra) is a thermodynamic (absolute) temperature scale named after Scottish engineer and physicist William John Macquorn Rankine. It is similar to the Kelvin scale, but the zero point is set at absolute zero, and it uses the Fahrenheit degree as its unit increment. This means that one Rankine degree is equal to one Fahrenheit degree, but the scales differ in their starting points; absolute zero on the Rankine scale is 0°Ra.

The Reaumur scale (°Re), created by French scientist Rene Antoine Ferchault de Reaumur, is a temperature scale in which the freezing and boiling points of water are defined as 0°Re and 80°Re respectively. This scale has been historically used in Europe, particularly in France, Germany, and Russia, before being replaced by the Celsius scale. The degree Reaumur is 1.25 times smaller than a degree Celsius and the scale is mostly of historical interest today.

History of Rankine and Reaumur

A brief history of the Rankine to Reaumur conversion: The Rankine scale, named after William Rankine, emerged in the 1850s during the industrial revolution, when precise temperature measurements were crucial. The Reaumur scale, although older and less common, was used in parts of Europe until the Celsius scale became widespread. The ability to convert between these scales remains a valuable tool for understanding historical temperature records and scientific documentation.

Solved Examples °Ra to °Re

Example Conversion 1:
If the temperature is 550°Ra, then the converted temperature in Reaumur is (550 - 491.67) × 4/9 °Re ≈ 25.85°Re.

Example Conversion 2:
For a temperature of 660°Ra, the equivalent in Reaumur is (660 - 491.67) × 4/9 °Re ≈ 74.81°Re.
