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:

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 (k_source):1 kcal/m³ = 4184.000002 joule per cubic meter (J/m³)

2. Target SI Bridge (k_target):1 Btu/ft³ = 37258.945798 joule per cubic meter (J/m³)

Step-by-step substitution for Kilocalorie/cubic meter → Btu/cubic foot:V(Btu/ft³) = V(kcal/m³) × ( 4184.000002 / 37258.945798 ) = V(kcal/m³) × 0.112295

Mathematical FormulaValue in Btu/cubic foot = Value in Kilocalorie/cubic meter × 0.11229518Direct computational formula applied for standard conversion.

Worked Example

For an engineering input of 250 kcal/m³, applying the conversion factor yields exactly 28.073795 Btu/ft³. At larger operational scale, 1000 Kilocalorie/cubic meter corresponds to 112.295179 Btu/ft³.

Inverse check: 1 Btu/ft³ = 8.905102 kcal/m³.
