The temperature measurable in theory on the thermodynamic temperature scale.
The temperature in Celsius degrees relative to the absolute zero at -273.16°C (the Kelvin scale) or in Fahrenheit degrees relative to the absolute zero at -459.69°F (the Rankine scale).

The temperature value relative to absolute zero. The absolute zero is the theoretical temperature at which molecular motion vanishes and a body would have no heat energy; the zero point of the Kelvin and Rankine temperature scales. Absolute zero may be interpreted as the temperature at which the volume of a perfect gas vanishes or, more generally, as the temperature of the cold source that would render a Carnot cycle 100% efficient. The value of absolute zero is now estimated to be −273.15°C, −459.67°F, 0 K, and 0°R.

However, neither the thermocouple nor the microhotplate thermal resistance can be directly calibrated as a temperature sensor by heating the entire chip containing the microhotplate because, unlike the heater resistance which responds to absolute temperature, the thermocouple and the thermal resistance respond to the temperature difference between the microhotplate and the substrate on which it is located.
It can be stated that a measurement accuracy of the absolute temperature of 10 mK with a resolution of 1 mK can be realized with high reliability.
y] and at on increasing temperature, it is not only the absolute temperature that must be regarded but also the temperature vs time relation, and the heating rate dT/ d[tau] in particular, as indicated by the following papers: [1-5], and by the authors' research results discussed in this paper.

They said they created moving vortices in a bismuth oxide superconductor film by applying a magnetic field above absolute temperature at 85 Kelvin (-188 C) and making slight changes in the magnetic field.
The absolute scale of temperature, on the other hand, is not arbitrary as there are many fundamental phenomena with absolute temperature dependence.
