Cubic Centimeter per Second to Liter per Hour (cm³/s to LPH)
Convert cm³/s to LPH — Flow Rate converter
Also written as cm3/s to LPH.
One cubic centimeter per second equals 3.6 LPH, so to convert cubic centimeters per second to liters per hour you multiply the value by 3.6. A cubic centimeter per second is larger than a liter per hour — going the other way, 1 LPH = 0.27777778 cm³/s. For example, 10 cm³/s = 36 LPH and 50 cm³/s = 180 LPH.
1 cm³/s = 3.6 LPH
Cubic Centimeter per Second to Liter per Hour formula
1 Cubic Centimeter per Second = 3.6 LPH
Worked examples
- 25 cm³/s = 90 LPH
- 100 cm³/s = 360 LPH

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 = 3.6 LPH.
