Unit Explanations
Rankine°R
Source UnitThe 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.
Current Use
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.
Fun Fact
Rankine is mostly used in the US, similar to how Kelvin is used worldwide.
Degree Réaumur°Ré
Target UnitThe degree Réaumur (°Ré) is a temperature scale developed by René Antoine Ferchault de Réaumur in the early 18th century. It is defined such that 0°Ré corresponds to the freezing point of water and 80°Ré corresponds to the boiling point of water at standard atmospheric pressure. The scale is based on the expansion of alcohol or mercury and is less commonly used today, primarily in some European countries. Despite its relative obscurity compared to Celsius and Fahrenheit, it represents a significant historical contribution to the field of thermometry, particularly in the context of early scientific studies in thermodynamics.
Current Use
Today, the degree Réaumur is rarely used in daily life or scientific research. However, it may still be encountered in specific contexts, such as certain industries that have historical ties to this measurement. Some culinary fields in France and Belgium may reference Réaumur for traditional recipes, while it also appears in historical documents and literature. Its use is primarily of academic interest, serving as a reminder of the development of temperature measurement.
Fun Fact
The Réaumur scale was once widely used in Europe, especially in France, but is now considered obsolete.

Definition
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.
History & Origin
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.
Current Use

Definition
The degree Réaumur (°Ré) is a temperature scale developed by René Antoine Ferchault de Réaumur in the early 18th century.

Despite its relative obscurity compared to Celsius and Fahrenheit, it represents a significant historical contribution to the field of thermometry, particularly in the context of early scientific studies in thermodynamics.
History & Origin
The degree Réaumur was first proposed by René Antoine Ferchault de Réaumur in 1731. De Réaumur was a French scientist who sought a practical temperature scale based on the properties of liquids. His scale was used extensively in Europe, particularly in France and Germany, for several centuries, primarily in scientific and industrial applications. Over time, however, it was overshadowed by the Celsius scale, which provided a more universal and straightforward application due to its alignment with the metric system.
Etymology: The term 'Réaumur' is derived from the name of the inventor, René Antoine Ferchault de Réaumur, reflecting his contributions to thermometry.
Current Use
Today, the degree Réaumur is rarely used in daily life or scientific research. However, it may still be encountered in specific contexts, such as certain industries that have historical ties to this measurement.

💡 Fun Facts
- •The Réaumur scale was once widely used in Europe, especially in France, but is now considered obsolete.
- •René Antoine Ferchault de Réaumur was also a pioneer in the study of thermodynamics and entomology.
- •The Réaumur scale is sometimes used in historical temperature records, especially in studies of 18th and 19th-century climates.
