How to convert liters per second to US gallons per minute
Flow-rate conversions help compare pump curves, pipe sizing inputs, irrigation notes, and water-system specifications.

Start with your value in liters per second, then apply the formula below. It stays visible so you can catch rounding mistakes instead of just copying the output.

Formula
gpm = L/s × 15.8503231415

Check whether gallons are US or imperial before using a flow result, then round to match the meter, pump chart, or engineering tolerance.

The US gallon and liter relationship is defined, but field flow measurements still depend on meter accuracy and operating conditions. This page displays converted values with up to 4 decimal places by default.
