Explanation

Formula: Liters per Minute = Gallons per Minute (US) × 3.785. Why: the route uses liters per second as the common basis, then applies the fixed US gallon definition together with the relevant per-minute or per-hour time scaling.

Gallons per Minute (US) (gpm): a US customary volumetric flow unit based on the US liquid gallon and commonly used in pumps, piping, and water systems.

Liters per Minute (L/min): a practical volumetric flow unit commonly used for pumps, plumbing, dosing, and process equipment.

This route is useful when translating between SI flow units and gallon- or cubic-foot-based reporting for pumps, piping, ventilation, and plant documentation.

This conversion is purely multiplicative because both units reduce through one liters-per-second flow basis with fixed unit-volume definitions and no offset.
