Cubic Centimeter per Second to Gallon (US) per Minute (cm³/s to GPM)
Convert cm³/s to GPM — Flow Rate converter
Also written as cm3/s to GPM.
One cubic centimeter per second equals 0.01585032 GPM, so to convert cubic centimeters per second to gallons (US) per minute you multiply the value by 0.01585032. A cubic centimeter per second is smaller than a gallon (US) per minute — going the other way, 1 GPM = 63.090196 cm³/s. For example, 10 cm³/s = 0.15850323 GPM and 50 cm³/s = 0.79251616 GPM.
1 cm³/s = 0.01585032 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 cm³/s = 0.01585032 GPM.
