Rankine to Fahrenheit: Definition, History, Engineering Uses, and Examples
Definition
Rankine (°R) is an absolute temperature scale based on the Fahrenheit scale, where 0°R = absolute zero (-459.67°F) and 491.67°R = freezing point of water (32°F). Fahrenheit (°F) is a temperature scale where 32°F = freezing and 212°F = boiling point of water. The conversion formula is: °F = °R - 459.67.
Origin or History
The Rankine scale was proposed by Scottish physicist William John Macquorn Rankine in 1859. It's an absolute temperature scale that uses the same degree size as Fahrenheit but starts at absolute zero, similar to how Kelvin relates to Celsius. Named after Rankine for his contributions to thermodynamics and engineering.
