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 91.73 degree Fahrenheit?


1 degree Fahrenheit = X+459.67 degree Rankine

91.73 degree Fahrenheit = Y degree Rankine

Assuming Y is the answer, and by substitution principle;

Y equals ( 91.73+459.67 ) over 1, where X is substituted by 91.73

(i.e.) Y = ( 91.73+459.67 ) / 1 = 551.4 degree Rankine

Answer is: 551.4 degree Rankine are equivalent to 91.73 degree Fahrenheit.
