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 kcal/m³ = 4184.000002 joule per cubic meter (J/m³)

2. Target SI Bridge (k_target):1 thm/gal = 2.787163 × 10¹⁰ joule per cubic meter (J/m³)

Step-by-step substitution for Kilocalorie/cubic meter → Therm/gallon (US):V(thm/gal) = V(kcal/m³) × ( 4184.000002 / 2.787163 × 10¹⁰ ) = V(kcal/m³) × 1.501168 × 10⁻⁷
