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)

2. Target SI Bridge (ktarget):1 kJ/m³ = 1000 joule per cubic meter (J/m³)
Step-by-step substitution for CHU/cubic foot → Kilojoule/cubic meter:V(kJ/m³) = V(CHU/ft³) × ( 67069.081154 / 1000 ) = V(CHU/ft³) × 67.069081
Mathematical FormulaValue in Kilojoule/cubic meter = Value in CHU/cubic foot × 67.06908115Direct computational formula applied for standard conversion.
Worked Example

To convert 2.5 CHU/cubic foot (CHU/ft³) to Kilojoule/cubic meter (kJ/m³): multiply 2.5 by 67.069081 to get 167.672703 kJ/m³. At an industrial engineering scale, 100 CHU/ft³ converts to 6706.908115 kJ/m³.
