The Rankine scale is an absolute temperature scale named after the Scottish engineer and physicist William John Macquorn Rankine. It is primarily used in thermodynamics and engineering fields in the United States. The Rankine scale sets its zero point at absolute zero, the same as the Kelvin scale, but uses degrees Fahrenheit for its increments. This means that a change of 1 degree Rankine is equivalent to a change of 1 degree Fahrenheit. The formula for converting Fahrenheit to Rankine is °R = °F + 459.67.
The Rankine scale is currently used in engineering fields, particularly in the United States, for thermodynamic calculations. Although it is not as widely used as it once was, Rankine is still relevant in certain niche areas where absolute temperature measurements are required. Industries such as aerospace, mechanical engineering, and HVAC (heating, ventilation, and air conditioning) utilize Rankine for specific applications.
Rankine is mostly used in the US, similar to how Kelvin is used worldwide.
The Réaumur scale, also known as the octogesimal scale, is a temperature scale defined by the freezing point of water at 0 degrees Réaumur (°Ré) and the boiling point at 80 degrees Réaumur. It was proposed by the French scientist René Antoine Ferchault de Réaumur in 1730. The scale was widely used in Europe, particularly in France and Germany, until the adoption of the Celsius scale. The Réaumur scale is based on the fractional division of the temperature range between freezing and boiling water, making it an important historical reference in thermometry.
Today, the Réaumur scale is largely obsolete and is rarely used in everyday temperature measurements. However, it still holds historical significance and is occasionally referenced in academic contexts or discussions about historical temperature scales. Certain niche industries, especially in food processing and brewing, may still employ the Réaumur scale in specific contexts.
The Réaumur scale was widely used in the 18th century, especially in France and Germany.

The Rankine scale was proposed by William John Macquorn Rankine in 1859. Rankine was a key figure in the development of thermodynamics and sought to create a scale that paralleled Kelvin's absolute temperature scale but used Fahrenheit degrees instead of Celsius. The Rankine scale became particularly useful in the United States, where Fahrenheit was the preferred temperature measurement system. Over time, the Rankine scale has been largely replaced by Kelvin in scientific contexts but remains in use in certain engineering fields.
Etymology: Named after William John Macquorn Rankine.

The Réaumur scale is based on the fractional division of the temperature range between freezing and boiling water, making it an important historical reference in thermometry.
The Réaumur temperature scale originated in the early 18th century, developed by the French physicist René Antoine Ferchault de Réaumur. He introduced the scale in 1730, creating a temperature measurement system based on the properties of water. The scale gained popularity in scientific and industrial applications, particularly in France and Germany, before the rise of the Celsius scale.
Etymology: The term 'Réaumur' is derived from the name of its inventor, René Antoine Ferchault de Réaumur, who was a prominent French scientist known for his contributions to thermometry and other fields.
Today, the Réaumur scale is largely obsolete and is rarely used in everyday temperature measurements. However, it still holds historical significance and is occasionally referenced in academic contexts or discussions about historical temperature scales.
