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

Converting Gallon (UK)/day (gal (UK)/d) to Liter/second (L/s) 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)/day equals 5.261678 × 10⁻⁵ Liter/second, while 1 L/s equals 19005.343053 gal (UK)/d.

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)/d = 5.261678 × 10⁻⁸ cubic meter per second (m³/s)
2. Target SI Bridge (ktarget):1 L/s = 0.001 cubic meter per second (m³/s)
Step-by-step substitution for Gallon (UK)/day → Liter/second:V(L/s) = V(gal (UK)/d) × ( 5.261678 × 10⁻⁸ / 0.001 ) = V(gal (UK)/d) × 5.261678 × 10⁻⁵

Worked Example

To convert 50 Gallon (UK)/day (gal (UK)/d) to Liter/second (L/s): multiply 50 by 5.261678 × 10⁻⁵ to get 0.00263084 L/s. At an industrial engineering scale, 1000 gal (UK)/d converts to 0.0526168 L/s.

Inverse check: 1 L/s = 19005.343053 gal (UK)/d.
