The difference of temperatures between the freezing- and boiling-points of water under standard atmospheric pressure shall be called 100 degrees. (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]
Some temperatures relating the Rankine scale to other temperature scales are shown in the table below. ... Freezing point of water [b] 273.15 K 491.67 °Ra 32 °F
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 ...
Cryogenicists use the Kelvin or Rankine temperature scale, both of which measure from absolute zero, rather than more usual scales such as Celsius which measures from the freezing point of water at sea level [9] [10] or Fahrenheit which measures from the freezing point of a particular brine solution at sea level. [11] [12]
The Newton scale is a temperature scale devised by ... the values for body temperature and the freezing and boiling point of water suggest a conversion factor ...
For temperature range: 173.15 K to 273.15 K or equivalently −100 °C to 0 °C At triple point An important basic value, which is not registered in the table, is the saturated vapor pressure at the triple point of water.
