Fahrenheit to Rankine

Fahrenheit is a temperature scale named after the German physicist Gabriel Fahrenheit (1686–1736), who proposed it in 1724. Rankine is a thermodynamic (absolute) temperature scale named after the Scottish engineer and physicist William John Macquorn Rankine, who proposed it in 1859.

Convert degrees Fahrenheit to degrees Rankine with this simple formula:

degrees Rankine = [°F] + 459.67

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

For example

let's convert 50 °F to degrees Rankine:

50 °F = ( 50 + 459.67 ) = 509.67 °R

The Fahrenheit scale and the Rankine scale are both used to measure temperature.


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.

Important Temperatures In Degrees Fahrenheit

Temperature Degrees Fahrenheit
Absolute Zero -459.67 °F
Freezing Point of Water 32 °F
Triple Point of Water 32.018 °F
Boiling Point of Water 212 °F


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.
