Current thermodynamic metrology relies on temperature scales (Fahrenheit, Celsius) derived from localized, Earth-specific atmospheric conditions. While the Kelvin scale successfully established an absolute zero baseline, its unit magnitude remains a historical artifact derived from the Celsius scale. As astrodynamics and extra-terrestrial metrology expand, this localized definition introduces unnecessary abstraction. This paper proposes the Absolute ("A") Scale: a universal temperature measurement system anchored exclusively by two invariant thermodynamic constants—Absolute Zero (0 °A) and the triple point of pure H₂O (100 °A). This centigrade-style framework provides a mathematically proportional, non-anthropocentric standard optimized for cosmological environments.
