Fahrenheit (°F) to Rankine (°R) Conversion
Fahrenheit
The Fahrenheit scale was developed by Daniel Gabriel Fahrenheit in 1724 and sets the freezing point of water at 32 °F and the boiling point at 212 °F, creating a 180-degree interval exactly 9/5 of the Celsius interval. Today the Fahrenheit scale is the official temperature scale of the United States and several Caribbean nations.
Rankine
The Rankine scale is an absolute temperature scale using the same degree size as Fahrenheit but with zero at absolute zero (−459.67 °F). It is to Fahrenheit what Kelvin is to Celsius. Used primarily in US aerospace engineering and thermodynamic cycle analysis where Fahrenheit-sized degrees are conventional but absolute temperature values are required. Water freezes at 491.67 °R and boils at 671.67 °R.

Frequently Asked Questions (FAQ)
What is the formula to convert Fahrenheit to Rankine?
The exact formula is °R = °F + 459.67. For example: 32°F = 491.67 °R and 212°F = 671.67 °R. This is one of the simplest temperature conversions because both scales use the same degree size.
What is 0 degrees Fahrenheit in Rankine?
0°F equals 459.67 °R. Using the formula: 0 + 459.67 = 459.67 °R. Because Rankine degrees are the same size as Fahrenheit degrees, you simply add the Fahrenheit–Rankine offset of 459.67.
