Unit Definitions
Rankine
The Rankine scale (symbol: °R) is an absolute temperature scale named after Scottish engineer William John Macquorn Rankine, who proposed it in 1859. The zero point of the Rankine scale is absolute zero, and a one-degree change in Rankine is equal to a one-degree change in Fahrenheit.
Fahrenheit
The Fahrenheit scale (symbol: °F) is a temperature scale based on one proposed by physicist Daniel Gabriel Fahrenheit in 1724. In this scale, the freezing point of water is 32°F and the boiling point is 212°F at standard atmospheric pressure.
Historical Context
The Rankine scale was developed in 1859 to provide an absolute temperature scale for engineering calculations while maintaining compatibility with the Fahrenheit scale that was already in common use.
