How to Convert Gallon (UK)/second to Liter/day

Converting Gallon (UK)/second (gal (UK)/s) to Liter/day (L/d) 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)/second equals 392782.176 Liter/day, while 1 L/d equals 2.54594 × 10⁻⁶ gal (UK)/s.

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)/s = 0.00454609 cubic meter per second (m³/s)
2. Target SI Bridge (ktarget):1 L/d = 1.157407 × 10⁻⁸ cubic meter per second (m³/s)
Step-by-step substitution for Gallon (UK)/second → Liter/day:V(L/d) = V(gal (UK)/s) × ( 0.00454609 / 1.157407 × 10⁻⁸ ) = V(gal (UK)/s) × 392782.176
Mathematical FormulaValue in Liter/day = Value in Gallon (UK)/second × 392782.176Direct computational formula applied for standard conversion.
Worked Example

To convert 120 Gallon (UK)/second (gal (UK)/s) to Liter/day (L/d): multiply 120 by 392782.176 to get 4.713386 × 10⁷ L/d. At an industrial engineering scale, 1000 gal (UK)/s converts to 3.927822 × 10⁸ L/d.

Inverse check: 1 L/d = 2.54594 × 10⁻⁶ gal (UK)/s.
