The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa.

In 1948, the Celsius scale was recalibrated by assigning the triple point temperature of water the value of 0.01 °C exactly [35] and allowing the melting point at standard atmospheric pressure to have an empirically determined value (and the actual melting point at ambient pressure to have a fluctuating value) close to 0 °C.
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 ...
The Hüttig temperature for a given material is = where is the absolute temperature of the material's bulk melting point (usually specified in Kelvin units) and is a unitless constant that is independent of the material, having the value = according to some sources, [4] [8] or = / according to other sources.
