Liter per Second to Gallon (US) per Second (LPS to gal/s)
Convert LPS to gal/s — Flow Rate converter
One liter per second equals 0.26417205 gal/s, so to convert liters per second to gallons (US) per second you multiply the value by 0.26417205. A liter per second is smaller than a gallon (US) per second — going the other way, 1 gal/s = 3.785412 LPS. For example, 10 LPS = 2.641721 gal/s and 50 LPS = 13.208603 gal/s.
1 LPS = 0.26417205 gal/s

Which gallon, and which trade
The single most expensive mistake in flow conversion is the gallon. A US liquid gallon is 3.785411784 litres; an imperial gallon is 4.54609 litres. US GPM and imperial GPM differ by about 20%, and pump datasheets frequently do not say which one they mean. Check the manufacturer's country of origin before trusting a GPM figure.
Different trades default to different units for the same physical quantity: HVAC and compressed air work in CFM, plumbing and pumps in GPM or LPM, and process and water engineering in m³/h or L/s. A specification that mixes them is usually quoting different equipment, not different flows. On this page, 1 LPS = 0.26417205 gal/s.
