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

Converting Cubic foot/kilogram (ft³/kg) to Gallon (US)/pound (gal/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 3.393106 Gallon (US)/pound, while 1 gal/lb equals 0.294715 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/lb = 0.0083454 cubic meter per kilogram (m³/kg)

Step-by-step substitution for Cubic foot/kilogram → Gallon (US)/pound:V(gal/lb) = V(ft³/kg) × ( 0.0283168 / 0.0083454 ) = V(ft³/kg) × 3.393106

Worked Example

Converting 250 ft³/kg yields an exact output of 848.27658 gal/lb in Gallon (US)/pound. Under higher industrial throughput, 100 ft³/kg translates to 339.310632 gal/lb.

Inverse check: 1 gal/lb = 0.294715 ft³/kg.
