How to Convert Cubic foot/kilogram to Gallon (UK)/pound

Converting Cubic foot/kilogram (ft³/kg) to Gallon (UK)/pound (gal (UK)/lb) is a core calculation in Specific Volume, which measures the volume occupied by a unit mass of material (the reciprocal of mass density). This calculation navigates the boundary between the International Metric System (SI) and British Imperial / US Customary engineering standards. In contemporary metrology, Imperial units are defined in terms of exact SI standards via international agreements—notably NIST SP 811 and the 1959 International Yard and Pound Agreement. Exactly 1 Cubic foot/kilogram equals 2.825352 Gallon (UK)/pound, while 1 gal (UK)/lb equals 0.353938 ft³/kg.

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 ft³/kg = 0.0283168 cubic meter per kilogram (m³/kg)

2. Target SI Bridge (k_target):1 gal (UK)/lb = 0.0100224 cubic meter per kilogram (m³/kg)

Step-by-step substitution for Cubic foot/kilogram → Gallon (UK)/pound:V(gal (UK)/lb) = V(ft³/kg) × ( 0.0283168 / 0.0100224 ) = V(ft³/kg) × 2.825352

Mathematical FormulaValue in Gallon (UK)/pound = Value in Cubic foot/kilogram × 2.8253519Direct computational formula applied for standard conversion.

Worked Example

For an engineering input of 75 ft³/kg, applying the conversion factor yields exactly 211.901393 gal (UK)/lb. At larger operational scale, 10000 Cubic foot/kilogram corresponds to 28253.519005 gal (UK)/lb.

Inverse check: 1 gal (UK)/lb = 0.353938 ft³/kg.
