Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (joule per cubic meter (J/m³)) without arbitrary rounding:

V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)

Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)

1. Source SI Bridge (k_source):1 MJ/m³ = 1000000 joule per cubic meter (J/m³)

2. Target SI Bridge (k_target):1 therm/gal (UK) = 2.320798 × 10¹⁰ joule per cubic meter (J/m³)

Step-by-step substitution for Megajoule/cubic meter → Therm/gallon (UK):V(therm/gal (UK)) = V(MJ/m³) × ( 1000000 / 2.320798 × 10¹⁰ ) = V(MJ/m³) × 4.308863 × 10⁻⁵
