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 therm/ft³ = 3.725895 × 10⁹ joule per cubic meter (J/m³)

2. Target SI Bridge (k_target):1 MJ/m³ = 1000000 joule per cubic meter (J/m³)

Step-by-step substitution for Therm/cubic foot → Megajoule/cubic meter:V(MJ/m³) = V(therm/ft³) × ( 3.725895 × 10⁹ / 1000000 ) = V(therm/ft³) × 3725.8947

Mathematical FormulaValue in Megajoule/cubic meter = Value in Therm/cubic foot × 3725.8947Direct computational formula applied for standard conversion.
