Delisle (°De): A Historical Temperature Scale

The Delisle scale, denoted as °De, was developed by French astronomer Joseph-Nicolas Delisle in the 18th century. This scale is unique in that it measures temperature in reverse; higher temperatures correspond to lower degree values. Although it has fallen out of common use, the Delisle scale remains a point of interest in the history of thermometry and the development of temperature measurement systems.

Rankine (°R): The Absolute Fahrenheit Scale

The Rankine scale, symbolized as °R, is an absolute temperature scale used mainly in engineering fields, particularly in the United States. It combines the Fahrenheit degree with the concept of absolute zero, starting at 0°R. The Rankine scale is essential in thermodynamic calculations where temperature differences are measured in Fahrenheit degrees, such as in aerospace and mechanical engineering applications.
