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

Converting Gallon (US)/pound (gal/lb) to Cubic foot/kilogram (ft³/kg) 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 Gallon (US)/pound equals 0.294715 Cubic foot/kilogram, while 1 ft³/kg equals 3.393106 gal/lb.

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 gal/lb = 0.0083454 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 Gallon (US)/pound → Cubic foot/kilogram:V(ft³/kg) = V(gal/lb) × ( 0.0083454 / 0.0283168 ) = V(gal/lb) × 0.294715

Worked Example

Evaluating an input of 120 Gallon (US)/pound (gal/lb) produces 35.365824 Cubic foot/kilogram (ft³/kg). In heavy-duty utility and industrial workloads, 100 gal/lb equals 29.47152 ft³/kg.

Inverse check: 1 ft³/kg = 3.393106 gal/lb.
