In next fields, kindly type your value in the text box under title [ From: ] to convert from fahrenheit to rankine (F to R). As you type your value, the answer will be automatically calculated and displayed in the text box under title [ To: ].

**Definitions:**

**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.

**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.

## How to Convert Degree Fahrenheit to Degree Rankine

*Example: How many degree Rankine are equivalent to 50.26 degree Fahrenheit?*

As;

1 degree Fahrenheit = X+459.67 degree Rankine

50.26 degree Fahrenheit = Y degree Rankine

Assuming Y is the answer, and by substitution principle;

Y equals ( 50.26+459.67 ) over 1, where X is substituted by 50.26

(i.e.) Y = ( 50.26+459.67 ) / 1 = 509.93 degree Rankine

Answer is: 509.93 degree Rankine are equivalent to 50.26 degree Fahrenheit.
