Rankine

The Rankine (°R) is an absolute temperature scale used primarily in thermodynamics. Like the Kelvin scale, it starts at absolute zero, the lowest possible temperature. The Rankine scale has the same increments as the Fahrenheit scale, so a temperature change of 1°R is equivalent to a change of 1°F. Absolute zero on the Rankine scale is 0°R, which corresponds to -459.67°F.

Origin:

The Rankine scale was developed by the Scottish engineer and physicist William John Macquorn Rankine in the 19th century, specifically in 1859. Rankine created this scale to provide an absolute temperature scale using Fahrenheit's temperature divisions, making it particularly useful for thermodynamic calculations in engineering and physics. The Rankine scale is still used in some fields, particularly in the United States for thermodynamic calculations in engineering applications, though the Kelvin scale is more widely used internationally in scientific contexts.

Reaumur

The Réaumur (°Ré) is a temperature scale in which the freezing point of water is defined as 0°Ré and the boiling point of water is 80°Ré, at standard atmospheric pressure. The scale divides the difference between the freezing and boiling points of water into 80 equal parts, with each degree representing an equal temperature interval.

Origin:

The Réaumur scale was developed by the French scientist René Antoine Ferchault de Réaumur in 1730. Réaumur created this scale based on the properties of water and the idea of dividing the temperature range between freezing and boiling points into 80 intervals, making it convenient for use in industries like brewing and metallurgy. The scale was once widely used in Europe, particularly in France, Germany, and parts of Russia. However, it was eventually supplanted by the Celsius scale, which became more universally adopted due to its simplicity and consistency with the metric system. Despite this, the Réaumur scale is still of historical interest and is sometimes used in specialized fields such as certain aspects of thermometry and scientific research.
