Gallon (UK) per Minute to Gallon (US) per Second (imp gal/min to gal/s)

Convert imp gal/min to gal/sFlow Rate converter

One gallon (UK) per minute equals 0.02001584 gal/s, so to convert gallons (UK) per minute to gallons (US) per second you multiply the value by 0.02001584. A gallon (UK) per minute is smaller than a gallon (US) per second — going the other way, 1 gal/s = 49.960436 imp gal/min. For example, 10 imp gal/min = 0.20015838 gal/s and 50 imp gal/min = 1.000792 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 imp gal/min = 0.02001584 gal/s.
