Absolute zero: Lowest recorded surface temperature on Earth [1] Fahrenheit's ice/water/salt mixture: Melting point of ice (at standard pressure) Average surface temperature on Earth (15 °C) Average human body temperature (37 °C) Highest recorded surface temperature on Earth [2] Boiling point of water (at standard pressure)
The scale was designed on the principle that "a unit of heat descending from a body A at the temperature T ° of this scale, to a body B at the temperature (T − 1)°, would give out the same mechanical effect, whatever be the number T."
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 ...
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 ...

Absolute temperature scale can refer to: Thermodynamic temperature, the absolute temperature; Kelvin scale, an absolute-temperature scale related to the Celsius scale; Rankine scale, an absolute-temperature scale related to the Fahrenheit scale; For a type of measuring system that begins at an absolute minimum (not necessarily a temperature ...
On the empirical temperature scales that are not referenced to absolute zero, a negative temperature is one below the zero point of the scale used. For example, dry ice has a sublimation temperature of −78.5 °C which is equivalent to −109.3 °F. [97] On the absolute Kelvin scale this temperature is 194.6 K.
