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 CHU/ft³ = 67069.081154 joule per cubic meter (J/m³)
2. Target SI Bridge (ktarget):1 therm/gal (UK) = 2.320799 × 10¹⁰ joule per cubic meter (J/m³)
Step-by-step substitution for CHU/cubic foot → Therm/gallon (UK):V(therm/gal (UK)) = V(CHU/ft³) × ( 67069.081154 / 2.320799 × 10¹⁰ ) = V(CHU/ft³) × 2.889913 × 10⁻⁶
