How to Convert Pound/cubic foot to Pound/gallon (UK)

Converting Pound/cubic foot (lb/ft³) to Pound/gallon (UK) (lb/gal (UK)) is a core calculation in Mass Density, which quantifies the concentration of physical mass contained within a unit volume of substance. 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 Pound/cubic foot equals 0.160544 Pound/gallon (UK), while 1 lb/gal (UK) equals 6.228835 lb/ft³.

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/ft³ = 16.018463 kilogram per cubic meter (kg/m³)

2. Target SI Bridge (k_target):1 lb/gal (UK) = 99.776373 kilogram per cubic meter (kg/m³)

Step-by-step substitution for Pound/cubic foot → Pound/gallon (UK):V(lb/gal (UK)) = V(lb/ft³) × ( 16.018463 / 99.776373 ) = V(lb/ft³) × 0.160544

Mathematical FormulaValue in Pound/gallon (UK) = Value in Pound/cubic foot × 0.16054365Direct computational formula applied for standard conversion.

Worked Example

To convert 120 Pound/cubic foot (lb/ft³) to Pound/gallon (UK) (lb/gal (UK)): multiply 120 by 0.160544 to get 19.265238 lb/gal (UK). At an industrial engineering scale, 2500 lb/ft³ converts to 401.359131 lb/gal (UK).

Inverse check: 1 lb/gal (UK) = 6.228835 lb/ft³.
