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:

Vtarget=Vsource×(ksource→SIktarget→SI)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 (ksource):1 cal/cm³ = 4186798.187954 joule per cubic meter (J/m³)
2. Target SI Bridge (ktarget):1 Btu/gal (UK) = 232079.9469 joule per cubic meter (J/m³)
Step-by-step substitution for Calorie (IT)/cubic centimeter → Btu (IT)/gallon (UK):V(Btu/gal (UK)) = V(cal/cm³) × ( 4186798.187954 / 232079.9469 ) = V(cal/cm³) × 18.040327
