Gallon (US) per Minute to Cubic Meter per Day (GPM to m³/d)
Convert GPM to m³/d — Flow Rate converter
Also written as GPM to m3/d.
One gallon (US) per minute equals 5.450993 m³/d, so to convert gallons (US) per minute to cubic meters per day you multiply the value by 5.450993. A gallon (US) per minute is larger than a cubic meter per day — going the other way, 1 m³/d = 0.18345281 GPM. For example, 10 GPM = 54.50993 m³/d and 50 GPM = 272.549648 m³/d.
1 GPM = 5.450993 m³/d

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 GPM = 5.450993 m³/d.
