The Rankine Scale is a temperature measurement that is still used in some scientific industries, although less commonly than the Celsius or Fahrenheit scales. It is a type of Kelvin scale, but uses Fahrenheit degrees instead of Celsius degrees. The Rankine Scale was named after its creator, William Rankine, and is often referred to as the absolute Fahrenheit scale. Synonyms for the Rankine Scale include the absolute temperature scale, the thermodynamic temperature scale, and the Kelvin Rankine scale. While the Rankine Scale is not as widely used today, it remains an important part of scientific history and a valuable tool for certain industries.
