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 (cubic meter per kilogram (m³/kg)) 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 m³/kg = 1 cubic meter per kilogram (m³/kg)

2. Target SI Bridge (k_target):1 ft³/kg = 0.0283168 cubic meter per kilogram (m³/kg)

Step-by-step substitution for Cubic meter/kilogram → Cubic foot/kilogram:V(ft³/kg) = V(m³/kg) × ( 1 / 0.0283168 ) = V(m³/kg) × 35.31467

Mathematical FormulaValue in Cubic foot/kilogram = Value in Cubic meter/kilogram × 35.31467Direct computational formula applied for standard conversion.

Worked Example

Converting 8 m³/kg yields an exact output of 282.51736 ft³/kg in Cubic foot/kilogram. Under higher industrial throughput, 1000 m³/kg translates to 35314.67 ft³/kg.

Inverse check: 1 ft³/kg = 0.0283168 m³/kg.
