Volumetric flow rate is volume per unit time. Pumps, taps and pipes are rated in L/min, L/s, m³/h or US gallons per minute depending on the manufacturer. One m³/h is about 16.67 L/min, and one US GPM is about 3.785 L/min. This converter is useful when sizing a pump, comparing shower heads (water-saving models are often below 9 L/min, about 2.4 GPM), or checking irrigation and HVAC specifications from different countries.
