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)

2. Target SI Bridge (ktarget):1 Btu/ft³ = 37258.934693 joule per cubic meter (J/m³)
Step-by-step substitution for Btu (IT)/gallon (UK) → Btu (IT)/cubic foot:V(Btu/ft³) = V(Btu/gal (UK)) × ( 232079.9469 / 37258.934693 ) = V(Btu/gal (UK)) × 6.22884
