Rankine To Fahrenheit Formula
Use this formula to convert a temperature in Rankine (K) to Fahrenheit (°R).
If required, there are worked examples below which use this formula to show how to convert a temperature in Rankine to a temperature in Fahrenheit.
As with any math calculation and conversion, it's good practice to double check your results. If you are using this formula for your own conversions, you can check your result with the Rankine to Fahrenheit calculator.
Temperature scales are usually named after the person who created them. The temperature scales used in this formula were created by William John Macquorn Rankine (1820-1872), and Daniel Gabriel Fahrenheit (1686–1736).
Given the Rankine scale was invented many years after the Fahrenheit scale, it's probable William Rankine also created this formula for converting Rankine to Fahrenheit.
How To Convert Rankine To Fahrenheit
Using the Rankine to Fahrenheit formula: Fahrenheit (°F) = Rankine - 459.67, these examples show how to convert a temperature in Rankine to Fahrenheit.
Worked Example 1
How To Convert 500 Rankine (°R) to Fahrenheit (°F)
| °F = | 500 - 459.67 |
| = | 40.33 °F |
| ∴ | therefore, 500 Rankine (°R) is equal to 40.33 Fahrenheit (°F) |

Worked Example 2
How To Convert 550 Rankine (°R) to Fahrenheit (°F)
| °F = | 550 - 459.67 |
| = | 90.33 °F |
| ∴ | therefore, 550 Rankine (°R) is equal to 90.33 Fahrenheit (°F) |

Albert Einstein & his impostor are shown for illustrative purposes.
Daniel Gabriel Fahrenheit (1686–1736), is the proponent of the Fahrenheit temperature scale.
