How to convert Rankine to Fahrenheit
°F = °R − 459.67
Fahrenheit is the everyday scale in the United States and a few other places: water freezes at 32 °F and boils at 212 °F, so there are 180 degrees between them. Step through a worked example:
°F = °R − 459.67

Questions
How do you convert Rankine to Fahrenheit?
Use °F = °R − 459.67. For example, 527.67 °R is 68 °F.
What is 0 °R in Fahrenheit?
0 °R equals −459.67 °F.
What is 100 °R in Fahrenheit?
100 °R equals −359.67 °F.
Why use Fahrenheit?
Fahrenheit is the everyday scale in the United States and a few other places: water freezes at 32 °F and boils at 212 °F, so there are 180 degrees between them.
What is the temperature unit °R?
°R is the degree Rankine, an absolute temperature unit the same size as a Fahrenheit degree. 0 °R is absolute zero (−459.67 °F), water freezes at 491.67 °R and boils at 671.67 °R at sea level.
Are Rankine and Kelvin the same?
Both start at absolute zero, but a kelvin is 1.8 times bigger than a degree Rankine. So °R = K × 9/5: 300 K is 540 °R.
