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 (J)) 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 (th) = 1054.350264 joule (J)
2. Target SI Bridge (ktarget):1 foe (kL) = 4.019293 × 10¹⁰ joule (J)
Step-by-step substitution for Btu (th) → Fuel oil equivalent @kiloliter:V(foe (kL)) = V(Btu (th)) × ( 1054.350264 / 4.019293 × 10¹⁰ ) = V(Btu (th)) × 2.623223 × 10⁻⁸
Mathematical FormulaValue in Fuel oil equivalent @kiloliter = Value in Btu (th) × 2.62322346 × 10⁻⁸Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 75 Btu (th), applying the conversion factor yields exactly 1.967418 × 10⁻⁶ foe (kL). At larger operational scale, 10000 Btu (th) corresponds to 0.000262322 foe (kL).
