From Celsius
TG = 2TC
Canonical reference
Definition & specification
The defining relationship is unchanged. Version 1.2 adds coordinated authorized translations while preserving the quantitative comparison introduced in Version 1.1; every earlier version remains permanently citable.
VERSION 1.2 · PUBLISHED ON ZENODO
Version 1.2
The Galliera Temperature Scale
The defining relationship remains exact and unchanged: TG = 2TC. Version 1.2 preserves that comparison and adds authorized Spanish, French, German, Italian, Brazilian Portuguese, Simplified Chinese, and Japanese editions.
Normative definition
The scale in two equations.
The definition is deliberately minimal.
Back to Celsius
TC = TG / 2
Canonical identity: Version 1.0 established TG = 2TC. Version 1.2 preserves that relationship unchanged; altering it would define a different scale.

Scope
What Version 1.2 adds — and what it does not change.
The definition stays fixed. This edition adds coordinated translations while retaining the quantitative rationale.
Definition unchanged
Galliera readings still satisfy TG = 2 TC and share the Celsius zero point.
Granularity quantified
Across 0–40 °C, the same physical range contains 40 Celsius, 72 Fahrenheit, and 80 Galliera one-degree intervals.
Precision claim unchanged
The extra whole-number intervals are a representational advantage, not extra sensor accuracy or metrological precision.
