Rankine
Rankine (°R) is an absolute temperature scale used primarily in engineering, where 0°R represents absolute zero and each degree Rankine is equivalent to one degree Fahrenheit.
History/Origin
The Rankine scale was introduced by William John Macquorn Rankine in 1859 as an absolute temperature scale based on the Fahrenheit degree, primarily used in the United States for thermodynamic calculations.
Current Use
Today, the Rankine scale is mainly used in certain engineering fields within the United States, especially in thermodynamics and heat transfer calculations, but it is largely replaced by the Kelvin scale in scientific contexts.
Triple Point Of Water
The triple point of water is the temperature and pressure at which water can coexist in solid, liquid, and gaseous states in thermodynamic equilibrium.
History/Origin
The triple point of water was first precisely defined in the 19th century and has since been used as a fundamental fixed point in temperature measurement, notably in the International Temperature Scale (ITS-90).
Current Use
The triple point of water serves as a standard calibration point for thermometers and is used to define the Kelvin temperature scale, with the unit symbol TPW representing this specific fixed point in temperature measurement.
