How to Convert Gallon (UK)/minute to Liter/minute

Converting Gallon (UK)/minute (gal (UK)/min) to Liter/minute (L/min) is a core calculation in Volumetric Flow Rate, which quantifies the volume of fluid passing through a designated conduit cross-section per unit of time. 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)/minute equals 4.54609 Liter/minute, while 1 L/min equals 0.219969 gal (UK)/min.

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 second (m³/s)) without arbitrary rounding:

Vtarget=Vsource×(ksource→SIktarget→SI)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 (ksource):1 gal (UK)/min = 7.576817 × 10⁻⁵ cubic meter per second (m³/s)
2. Target SI Bridge (ktarget):1 L/min = 1.666667 × 10⁻⁵ cubic meter per second (m³/s)
Step-by-step substitution for Gallon (UK)/minute → Liter/minute:V(L/min) = V(gal (UK)/min) × ( 7.576817 × 10⁻⁵ / 1.666667 × 10⁻⁵ ) = V(gal (UK)/min) × 4.54609
Mathematical FormulaValue in Liter/minute = Value in Gallon (UK)/minute × 4.54609Direct computational formula applied for standard conversion.
Worked Example

Evaluating an input of 120 Gallon (UK)/minute (gal (UK)/min) produces 545.5308 Liter/minute (L/min). In heavy-duty utility and industrial workloads, 5000 gal (UK)/min equals 22730.45 L/min.

Inverse check: 1 L/min = 0.219969 gal (UK)/min.
