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 79.81 degree Fahrenheit?
As;
1 degree Fahrenheit = X+459.67 degree Rankine
79.81 degree Fahrenheit = Y degree Rankine
Assuming Y is the answer, and by substitution principle;
Y equals ( 79.81+459.67 ) over 1, where X is substituted by 79.81
(i.e.) Y = ( 79.81+459.67 ) / 1 = 539.48 degree Rankine
Answer is: 539.48 degree Rankine are equivalent to 79.81 degree Fahrenheit.
