Gallon (US) per Minute to Cubic Centimeter per Second (GPM to cm³/s)
Convert GPM to cm³/s — Flow Rate converter
Also written as GPM to cm3/s.
One gallon (US) per minute equals 63.090196 cm³/s, so to convert gallons (US) per minute to cubic centimeters per second you multiply the value by 63.090196. A gallon (US) per minute is larger than a cubic centimeter per second — going the other way, 1 cm³/s = 0.01585032 GPM. For example, 10 GPM = 630.901964 cm³/s and 50 GPM = 3154.51 cm³/s.
1 GPM = 63.090196 cm³/s
Gallon (US) per Minute to Cubic Centimeter per Second formula
1 Gallon (US) per Minute = 63.090196 cm³/s
Worked examples
- 25 GPM = 1577.25 cm³/s
- 100 GPM = 6309.02 cm³/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 GPM = 63.090196 cm³/s.
