Cubic Meter per Day to Gallon (US) per Minute (m³/d to GPM)

Convert m³/d to GPMFlow Rate converter

Also written as m3/d to GPM.

One cubic meter per day equals 0.18345281 GPM, so to convert cubic meters per day to gallons (US) per minute you multiply the value by 0.18345281. A cubic meter per day is smaller than a gallon (US) per minute — going the other way, 1 GPM = 5.450993 m³/d. For example, 10 m³/d = 1.834528 GPM and 50 m³/d = 9.172641 GPM.

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 m³/d = 0.18345281 GPM.
