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 lb/gal (UK) = 99.776373 kilogram per cubic meter (kg/m³)

2. Target SI Bridge (k_target):1 lb/ft³ = 16.018463 kilogram per cubic meter (kg/m³)

Step-by-step substitution for Pound/gallon (UK) → Pound/cubic foot:V(lb/ft³) = V(lb/gal (UK)) × ( 99.776373 / 16.018463 ) = V(lb/gal (UK)) × 6.228835

Mathematical FormulaValue in Pound/cubic foot = Value in Pound/gallon (UK) × 6.22883549Direct computational formula applied for standard conversion.

Worked Example

Converting 36 lb/gal (UK) yields an exact output of 224.238078 lb/ft³ in Pound/cubic foot. Under higher industrial throughput, 480 lb/gal (UK) translates to 2989.841036 lb/ft³.

Inverse check: 1 lb/ft³ = 0.160544 lb/gal (UK).
