Rankine (°R) – The Engineering Absolute Scale

The Rankine scale is an absolute temperature scale similar to Kelvin but based on Fahrenheit increments. It is used mainly in thermodynamic calculations, particularly in the United States.

History of the Rankine Scale

Developed by William Rankine in 1859, this scale is designed for engineering applications where Fahrenheit is commonly used.

Usage and Applications

Thermodynamics:Used in heat and energy calculations.
Engineering:Common in power plants and refrigeration.
