About the rankine
The Rankine scale was proposed by Scottish engineer William John Macquorn Rankine in 1859. It is an absolute scale using Fahrenheit-sized degrees.
In everyday use the rankine appears in thermodynamic engineering calculations in the US, especially in HVAC and combustion. As a point of reference: standard room temperature (72 F) is about 531.67 Rankine.
