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 Btu/gal (UK) = 232079.9469 joule per cubic meter (J/m³)
2. Target SI Bridge (ktarget):1 kcal/m³ = 4186.798188 joule per cubic meter (J/m³)
Step-by-step substitution for Btu (IT)/gallon (UK) → Kilocalorie (IT)/cubic meter:V(kcal/m³) = V(Btu/gal (UK)) × ( 232079.9469 / 4186.798188 ) = V(Btu/gal (UK)) × 55.431367
Mathematical FormulaValue in Kilocalorie (IT)/cubic meter = Value in Btu (IT)/gallon (UK) × 55.431367Direct computational formula applied for standard conversion.
