The Rankine temperature scale was proposed by William John Macquorn Rankine in 1859 similarly to Kelvin temperature scale. The zero absolute at Rankine scale is also 0 K, and degree of Rankine is the same than Fahrenheit degree. The Rankine is represented as °R after the value, and sometimes like °RA.
The Fahrenheit temperature scale was proposed by Daniel Gabriel Fahrenheit in 1724 with the idea of starting from a brine solution freezes as 0, and 96 is the average temperature of human body. Its unit is represented with ℉ after the value.
The Fahrenheit values are calculated from Rankine values by substracting 459.67.
