Volume Flow Rate Converter

Convert common liquid and gas volume-flow units through liters per second.

Formula and conventions

Convert the input to L/s, then divide by the target unit’s L/s factor: L/min ÷ 60; L/s unchanged; m³/h × 1000 ÷ 3600; m³/s × 1000; U.S. gal/min × 3.785411784 ÷ 60; imperial gal/min × 4.54609 ÷ 60; ft³/min × 28.316846592 ÷ 60. The gallon and cubic-foot factors are exact.

Worked example

1 U.S. gal/min = 3.785411784 L/min; 1 imperial gal/min = 4.54609 L/min.

Conversions are fixed-volume conversions. No mass-flow conversion or gas standard-condition correction is applied.

Frequently asked questions

Are U.S. and imperial gallons the same?

No. A U.S. gallon is 3.785411784 L and an imperial gallon is 4.54609 L.

Does this apply a gas pressure or temperature correction?

No. It converts fixed volume-flow units only; it does not adjust gas volumes to standard or actual conditions.

Does it convert mass flow?

No. This tool converts volume per time and does not infer a fluid density.
