Gallon (US) per Second to Cubic Centimeter per Second (gal/s to cm³/s)
Convert gal/s to cm³/s — Flow Rate converter
Also written as gal/s to cm3/s.
One gallon (US) per second equals 3785.41 cm³/s, so to convert gallons (US) per second to cubic centimeters per second you multiply the value by 3785.41. A gallon (US) per second is larger than a cubic centimeter per second — going the other way, 1 cm³/s = 0.0002641721 gal/s. For example, 10 gal/s = 37854.12 cm³/s and 50 gal/s = 189270.59 cm³/s.
1 gal/s = 3785.41 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 gal/s = 3785.41 cm³/s.
