The Rankine scale (/ ˈ r æ ŋ k ɪ n / RANG-kin) is an absolute scale of thermodynamic temperature named after the University of Glasgow engineer and physicist Macquorn Rankine, who proposed it in 1859.
In 1859 he proposed the Rankine scale of temperature, an absolute or thermodynamic scale whose degree is equal to a Fahrenheit degree. In 1862, Rankine expanded Lord Kelvin’s theory of universal heat death and, along with Kelvin himself, formulated the heat death paradox, which disproves the possibility of an infinitely old universe.

This definition also precisely related the Celsius scale to the Kelvin scale, which defines the SI base unit of thermodynamic temperature with symbol K. Absolute zero, the lowest temperature possible, is defined as being exactly 0 K and −273.15 °C. Until 19 May 2019, the temperature of the triple point of water was defined as exactly 273.16 ...
A unit increment of one kelvin is exactly 1.8 times one degree Rankine; thus, to convert a specific temperature on the Kelvin scale to the Rankine scale, x K = 1.8 x °R, and to convert from a temperature on the Rankine scale to the Kelvin scale, x °R = x /1.8 K. Consequently, absolute zero is "0" for both scales, but the melting point of ...
(The same increment as the Celsius scale) Thomson's best estimates at the time were that the temperature of freezing water was 273.7 K and the temperature of boiling water was 373.7 K. [33] These two properties would be featured in all future versions of the Kelvin scale, although it was not yet known by that name.
He developed the Rankine scale, a Fahrenheit-based equivalent to the Celsius-based Kelvin scale of temperature. Rankine developed a complete theory of the steam engine and indeed of all heat engines. His manuals of engineering science and practice were used for many decades after their publication in the 1850s and 1860s.

Original – William Rankine, engineer and physicist, one of the founders of thermodynamics. Reason After seeing how good of quality Annan's picture of Livingstone was, I looked to see what else he had. Rather a lot, actually, a lot of it connected with Edinburgh and Glasgow. So, William Rankine. He developed the Rankine temperature scale ...
