How to Convert Rankine to Fahrenheit

Thermometers measure temperature and come in many forms and sizes

Convert degrees Rankine to degrees Fahrenheit with this simple formula:

degrees Fahrenheit = [°R] - 459.67

Insert the [°R] temperature measurement in the formula and then solve to find the result.

For example, let's convert 50 °R to degrees Fahrenheit:

50 °R = ( 50 - 459.67 ) = -409.67 °F

Rankine and Fahrenheit are both units used to measure temperature. Keep reading to learn more about each unit of measure.


The Rankine scale is an absolute temperature scale that uses absolute zero as the starting point, much like the Kelvin scale. The key difference between the Rankine scale and the Kelvin scale is that an increment of one degree rankine is equal to an increment of one degree Fahrenheit, not Celsius as in the Kelvin scale. The base of the Rankine scale starts at absolute zero, thus 0 degrees rankine are equal to −459.67 degrees Fahrenheit.

Rankine can be abbreviated as R, and are also sometimes abbreviated as Ra. For example, 1 degree Rankine can be written as 1 °R or 1 Ra.

The Fahrenheit scale is a temperature scale that defines the melting point of water as 32 degrees and the boiling point of water at 212 degrees. There are 180 intervals between 32 °F and 212 °F, each corresponding to one degree.

The degree Fahrenheit is a US customary and imperial unit of temperature. Fahrenheit can be abbreviated as F, for example 1 degree Fahrenheit can be written as 1 °F.
