  2. Rankine scale - Wikipedia

    en.wikipedia.org/wiki/Rankine_scale

    The Rankine scale is used in engineering systems where heat computations are done using degrees Fahrenheit. [3] The symbol for degrees Rankine is °R [2] (or °Ra if necessary to distinguish it from the Rømer and Réaumur scales). By analogy with the SI unit kelvin, some authors term the unit Rankine, omitting the degree symbol. [4] [5]

    en.wikipedia.org/wiki/William_Rankine

    William John Macquorn Rankine FRSE FRS (/ ˈ r æ ŋ k ɪ n /; 5 July 1820 – 24 December 1872) was a Scottish mathematician and physicist.He was a founding contributor, with Rudolf Clausius and William Thomson (Lord Kelvin), to the science of thermodynamics, particularly focusing on its First Law.

    1854 – Rankine introduces his thermodynamic function, later identified as entropy; 1856 – August Krönig publishes an account of the kinetic theory of gases, probably after reading Waterston's work; 1857 – Clausius gives a modern and compelling account of the kinetic theory of gases in his On the nature of motion called heat

    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.

  8. Thermodynamic temperature - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_temperature

    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 ...

  9. Scale of temperature - Wikipedia

    en.wikipedia.org/wiki/Scale_of_temperature

    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 ...
