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 (kilogram per cubic meter (kg/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 gr/gal (UK) = 0.0142538 kilogram per cubic meter (kg/m³)

2. Target SI Bridge (k_target):1 mg/m³ = 1 × 10⁻⁶ kilogram per cubic meter (kg/m³)

Step-by-step substitution for Grain/gallon (UK) → Milligram/cubic meter:V(mg/m³) = V(gr/gal (UK)) × ( 0.0142538 / 1 × 10⁻⁶ ) = V(gr/gal (UK)) × 14253.765488
