Add 459.67 to the Fahrenheit value. For example, 72 °F + 459.67 = 531.67 °R.
98.6 °F equals 558.27 °R.
The Rankine scale was proposed by Scottish physicist William John Macquorn Rankine in 1859 as an absolute temperature scale using Fahrenheit-sized degrees.
Physically no, because temperatures below absolute zero (-459.67 °F) do not occur in classical thermodynamics. Mathematically, any °F below -459.67 would give a negative °R.
