**Definitions:**

**Rankine** (abbreviations: **R, or °R, or deg R**): is a thermodynamic temperature based on an absolute scale named with regard to the Glasgow University engineer and physicist William John Macquorn Rankine, who proposed it in 1859.

**Fahrenheit** (abbreviations: **F, or °F, or deg F**): is a temperature scale based on one proposed in 1724 by Amsterdam-based physicist Daniel Gabriel Fahrenheit (1686–1736), with regard to whom the scale is named.

## How to Convert Degree Rankine to Degree Fahrenheit

*Example: How many degree Fahrenheit are equivalent to 24.39 degree Rankine?*

As;

1 degree Rankine = X-459.67 degree Fahrenheit

24.39 degree Rankine = Y degree Fahrenheit

Assuming Y is the answer, and by substitution principle;

Y equals ( 24.39-459.67 ) over 1, where X is substituted by 24.39

(i.e.) Y = ( 24.39-459.67 ) / 1 = -435.28 degree Fahrenheit

Answer is: -435.28 degree Fahrenheit are equivalent to 24.39 degree Rankine.
