About volumetric flow rate units

Volumetric flow rate is the volume of fluid passing a point per unit time. Pumps and plumbing in the US are rated in gallons per minute, fans and HVAC in cubic feet per minute, and process equipment elsewhere in m³/h or L/min.

Frequently asked questions

What is the SI unit of volumetric flow rate?

This converter uses the cubic meter per second (m³/s) as its reference unit; every other unit is defined relative to it.

How many volumetric flow rate units can I convert?

17 units are supported here, across SI, Metric, US customary, Imperial systems. Every pair can be converted in both directions.

Does this volumetric flow rate converter work offline?

Yes. Once the page has loaded, every calculation runs locally in your browser — nothing is sent to a server.
