How to Convert Liter/hour to Gallon (US)/second

Converting Liter/hour (L/h) to Gallon (US)/second (gal (US)/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 Liter/hour equals 7.338113 × 10⁻⁵ Gallon (US)/second, while 1 gal (US)/s equals 13627.482422 L/h.

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 L/h = 2.777778 × 10⁻⁷ cubic meter per second (m³/s)
2. Target SI Bridge (ktarget):1 gal (US)/s = 0.00378541 cubic meter per second (m³/s)
Step-by-step substitution for Liter/hour → Gallon (US)/second:V(gal (US)/s) = V(L/h) × ( 2.777778 × 10⁻⁷ / 0.00378541 ) = V(L/h) × 7.338113 × 10⁻⁵

Worked Example

Evaluating an input of 50 Liter/hour (L/h) produces 0.00366906 Gallon (US)/second (gal (US)/s). In heavy-duty utility and industrial workloads, 10000 L/h equals 0.733811 gal (US)/s.

Inverse check: 1 gal (US)/s = 13627.482422 L/h.
