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 kJ/m³ = 1000 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 Kilojoule/cubic meter → Btu (IT)/gallon (UK):V(Btu/gal (UK)) = V(kJ/m³) × ( 1000 / 232079.9469 ) = V(kJ/m³) × 0.00430886
Mathematical FormulaValue in Btu (IT)/gallon (UK) = Value in Kilojoule/cubic meter × 0.00430886Direct computational formula applied for standard conversion.
Worked Example

Converting 15 kJ/m³ yields an exact output of 0.0646329 Btu/gal (UK) in Btu (IT)/gallon (UK). Under higher industrial throughput, 5000 kJ/m³ translates to 21.5443 Btu/gal (UK).

Inverse check: 1 Btu/gal (UK) = 232.079947 kJ/m³.
