How to Convert Pound/gallon (UK) to Kilogram/cubic meter

Converting Pound/gallon (UK) (lb/gal (UK)) to Kilogram/cubic meter (kg/m³) 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/gallon (UK) equals 99.776373 Kilogram/cubic meter, while 1 kg/m³ equals 0.0100224 lb/gal (UK).

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/gal (UK) = 99.776373 kilogram per cubic meter (kg/m³)

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

Step-by-step substitution for Pound/gallon (UK) → Kilogram/cubic meter:V(kg/m³) = V(lb/gal (UK)) × ( 99.776373 / 1 ) = V(lb/gal (UK)) × 99.776373

Mathematical FormulaValue in Kilogram/cubic meter = Value in Pound/gallon (UK) × 99.77637318Direct computational formula applied for standard conversion.

Worked Example

For an engineering input of 36 lb/gal (UK), applying the conversion factor yields exactly 3591.949434 kg/m³. At larger operational scale, 240 Pound/gallon (UK) corresponds to 23946.329563 kg/m³.

Inverse check: 1 kg/m³ = 0.0100224 lb/gal (UK).
