First, we have to know about the conversion formula which was written above. Here, T(F) represents the temperature in Fahrenheit and T(R) represent the temperature in Rankine. A temperature difference of 1 degree Fahrenheit is the equivalent of a temperature difference of 0.556 degrees Celcius.

## Rankine to Fahrenheit

A degree on the Fahrenheit scale is 1/180 of the interval between the freezing point and the boiling point of water.-459.67 Degrees Fahrenheit is -Absolute zero. In the mid-late 20th century the Fahrenheit scale was replaced by Celcius, and it becomes the official scale of the United States, Cayman Islands, and Belize. When the equal amounts of ice, water, and salt are mixed, the Fahrenheit pioneered the manufacture of thermometers using mercury and established 0 degrees Fahrenheit as the stabilized

temperature. In Fahrenheit, the normal human body temperature as 98.6 degrees Fahrenheit and freezing temperature of water have been redefined as exactly 32 degrees Fahrenheit.

The temperature T in degrees Rankine (R) is equal to the temperature T in Fahrenheit (F) plus 459.67:

1 Degree Rankine is equal to -458.67 degrees Fahrenheit.

1 Degree Rankine is equal to -272.592 degrees Celcius.

0 Degree Kelvin is equal to 0 degrees Rankine.

** For Example**

Convert 40 degrees Rankine into degrees Fahrenheit.

For this conversion, we just put this in the above formula and do calculation properly and get the answer is -419.67 degrees Fahrenheit

** Formula**

T(°F) + 459.67= T(°R), this is the formula which will be used for the conversion purpose, well according to this formula all you have to do is to add a value of 459.67 to the value of ranking to covert Rankine to Fahrenheit, this is as simple as addition.
