How to Convert Gallon (UK)/pound to Cubic inch/pound

Converting Gallon (UK)/pound (gal (UK)/lb) to Cubic inch/pound (in³/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 Gallon (UK)/pound equals 277.419433 Cubic inch/pound, while 1 in³/lb equals 0.00360465 gal (UK)/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 (UK)/lb = 0.0100224 cubic meter per kilogram (m³/kg)

2. Target SI Bridge (k_target):1 in³/lb = 3.612729 × 10⁻⁵ cubic meter per kilogram (m³/kg)

Step-by-step substitution for Gallon (UK)/pound → Cubic inch/pound:V(in³/lb) = V(gal (UK)/lb) × ( 0.0100224 / 3.612729 × 10⁻⁵ ) = V(gal (UK)/lb) × 277.419433

Mathematical FormulaValue in Cubic inch/pound = Value in Gallon (UK)/pound × 277.41943308Direct computational formula applied for standard conversion.

Worked Example

For an engineering input of 75 gal (UK)/lb, applying the conversion factor yields exactly 20806.457481 in³/lb. At larger operational scale, 240 Gallon (UK)/pound corresponds to 66580.663939 in³/lb.

Inverse check: 1 in³/lb = 0.00360465 gal (UK)/lb.
