Milliliter per Second to Liter per Second (mL/s to LPS)
Convert mL/s to LPS — Flow Rate converter
One milliliter per second equals 0.001 LPS, so to convert milliliters per second to liters per second you multiply the value by 0.001. A milliliter per second is smaller than a liter per second — going the other way, 1 LPS = 1000 mL/s. For example, 10 mL/s = 0.01 LPS and 50 mL/s = 0.05 LPS.
1 mL/s = 0.001 LPS
Milliliter per Second to Liter per Second formula
1 Milliliter per Second = 0.001 LPS
Worked examples
- 25 mL/s = 0.025 LPS
- 100 mL/s = 0.1 LPS

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 mL/s = 0.001 LPS.
Frequently asked questions
