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]
* Normal human body temperature is 36.8 °C ±0.7 °C, or 98.2 °F ±1.3 °F. The commonly given value 98.6 °F is simply the exact conversion of the nineteenth-century German standard of 37 °C. Since it does not list an acceptable range, it could therefore be said to have excess (invalid) precision.

Common scales of temperature measured in degrees: Celsius (°C) Fahrenheit (°F) Rankine (°R or °Ra), which uses the Fahrenheit scale, adjusted so that 0 degrees Rankine is equal to absolute zero. Unlike the degree Fahrenheit and degree Celsius, the kelvin is no longer referred to or written as a degree (but was before 1967 [1] [2] [3]). The ...
Also the copy is blurred up enough to give you the impression that maybe what it really means is 1.36 W −1 cm −1 K −1 and 78.6 Btu hr −1 ft −1 F −1 and a type-head that got overdue for its cleaning since the secretary had a tall heap of papers on her desk and if that is the case then the multilingual expression is perfectly ...
The kelvin is the fraction 1/273.16 of the thermodynamic temperature of the triple point of water. For practical measurements, the International Temperature Scale of 1990 defines several fixed points and interpolation procedures.
