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 61.95 degree Rankine?
As;
1 degree Rankine = X-459.67 degree Fahrenheit
61.95 degree Rankine = Y degree Fahrenheit
Assuming Y is the answer, and by substitution principle;
Y equals ( 61.95-459.67 ) over 1, where X is substituted by 61.95
(i.e.) Y = ( 61.95-459.67 ) / 1 = -397.72 degree Fahrenheit
Answer is: -397.72 degree Fahrenheit are equivalent to 61.95 degree Rankine.
