Gallon (UK) per Minute to Cubic Foot per Second (imp gal/min to CFS)
Convert imp gal/min to CFS — Flow Rate converter
One gallon (UK) per minute equals 0.0026757284 CFS, so to convert gallons (UK) per minute to cubic feet per second you multiply the value by 0.0026757284. A gallon (UK) per minute is smaller than a cubic foot per second — going the other way, 1 CFS = 373.730012 imp gal/min. For example, 10 imp gal/min = 0.02675728 CFS and 50 imp gal/min = 0.13378642 CFS.
1 imp gal/min = 0.0026757284 CFS

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 = 0.0026757284 CFS.
