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 Btu/ft³ = 37258.945798 joule per cubic meter (J/m³)

2. Target SI Bridge (k_target):1 kcal/m³ = 4184.000002 joule per cubic meter (J/m³)

Step-by-step substitution for Btu/cubic foot → Kilocalorie/cubic meter:V(kcal/m³) = V(Btu/ft³) × ( 37258.945798 / 4184.000002 ) = V(Btu/ft³) × 8.905102

Mathematical FormulaValue in Kilocalorie/cubic meter = Value in Btu/cubic foot × 8.90510176Direct computational formula applied for standard conversion.

Worked Example

To convert 12 Btu/cubic foot (Btu/ft³) to Kilocalorie/cubic meter (kcal/m³): multiply 12 by 8.905102 to get 106.861221 kcal/m³. At an industrial engineering scale, 480 Btu/ft³ converts to 4274.448846 kcal/m³.

Inverse check: 1 kcal/m³ = 0.112295 Btu/ft³.
