What are Thermodynamic Temperature Scales?
Temperature is an intensive thermodynamic state variable measuring average kinetic energy of constituent particles. The SI base unit is the Kelvin (K), anchored at absolute zero (0 K) and the Boltzmann constant $k_B = 1.380649 \times 10^{-23}\,\text{J/K}$.
Unlike affine units that scale multiplicatively, temperature scales feature distinct zero offsets ($0\,^\circ\text{C} = 273.15\,\text{K} = 32\,^\circ\text{F}$), necessitating coupled scale and intercept conversion algorithms.
