Rømer (°Rø)
Definition
Rømer (°Rø) is a temperature scale where 0°Rø was set to the freezing point of brine, 7.5°Rø to the freezing point of water, and 60°Rø to the boiling point of water.
History
The Rømer scale was created in 1701 by Ole Christensen Rømer, a Danish astronomer. Fahrenheit visited Rømer and was inspired by his work, later developing his own scale based on similar reference points.
Current use
The Rømer scale is no longer used practically. It is notable in the history of thermometry as the scale that inspired Fahrenheit's work, and appears in academic discussions of temperature measurement history.
Rankine (°R)
Definition
Rankine (°R) is an absolute temperature scale where 0°R equals absolute zero (−459.67°F). Each Rankine degree equals one degree Fahrenheit.
History
The Rankine scale was proposed in 1859 by William John Macquorn Rankine, a Scottish physicist and engineer. It was designed as the Fahrenheit-based equivalent of the Kelvin scale for use in thermodynamic engineering.
Current use
Rankine is used primarily in American engineering and thermodynamics, particularly in the aerospace and HVAC industries. Some US engineering textbooks and thermodynamic tables reference Rankine temperatures.
