(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] These two properties would be featured in all future versions of the Kelvin scale, although it was not yet known by that name.
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)
To create ice XVII, the researchers first produced filled ice in a stable phase named C 0 from a mixture of hydrogen (H 2) and water (H 2 O), using temperatures from 100 to 270 K (−173 to −3 °C; −280 to 26 °F) and pressures from 360 to 700 MPa (52,000 to 102,000 psi; 3,600 to 6,900 atm), and C 2 are all stable solid phases of a mixture ...
The degree Celsius (°C) can refer to a specific temperature on the Celsius scale as well as a unit to indicate a temperature interval (a difference between two temperatures). From 1744 until 1954, 0 °C was defined as the freezing point of water and 100 °C was defined as the boiling point of water, both at a pressure of one standard atmosphere .

The kelvin was defined so that the triple point of water is exactly 273.16 K, but that changed with the 2019 revision of the SI, where the kelvin was redefined so that the Boltzmann constant is exactly 1.380 649 × 10 −23 J⋅K −1, and the triple point of water became an experimentally measured constant.
