What Is a Volumetric Flow Rate Converter?

A volumetric flow rate converter converts between different flow rate measurement units.

Supported Units

  • m3/s — SI unit. Cubic meters per second.
  • L/min — Liters per minute. Common industrial.
  • L/h — Liters per hour.
  • gal/min (US) — US gallons per minute.
  • m3/h — Cubic meters per hour.

How Does Volumetric Flow Rate Converter Work?

1 m3/s = 60,000 L/min, 1 L/min = 0.2642 gal/min (US), 1 m3/h = 16.667 L/min.

How to Use This Tool

  1. Enter a numeric value — Type the measurement you want to convert.
  2. Select the source unit — Choose the unit you are converting from.
  3. Read the results — The tool instantly displays equivalents in every supported unit.
