Liters per Second to Gallons per Minute (US)

Snapshot

1 Liter per Second equals 15.85 Gallons per Minute (US). Conversion Encyclopedia uses the same fixed conversion basis across the calculator, common values, and reverse page for this page.

Reference basis: This conversion uses a fixed factor based on time-normalized rate definitions.
Example: For 0.1 Liters per Second, the result equals 1.585 Gallons per Minute (US).
Use the reverse page if you need the opposite direction with the same basis.

Full API documentation

Explanation

Formula: Gallons per Minute (US) = Liters per Second × 15.85. 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.

Liters per Second (L/s): an SI-style volumetric flow unit used to express how many liters move each second.

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.

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.

Method & Reference

Method basis: exact conversion formula shown in Snapshot.
Applied factor: 1 Liter per Second = 15.85 Gallons per Minute (US).
Consistency rule: calculator output and table values use the same constants and rounding policy.
