Convert volumetric flow rate between metric, US and imperial units. It is designed for pumps, pipes, HVAC and ventilation, irrigation, water supply and industrial process work.
Flow rate is volume per unit time; see the volume converter and time converter, and the pressure converter for pump head.
Compare pump ratings in GPM, L/min and m³/h when sizing pipes and equipment.
Convert fan airflow between CFM and m³/h for ducts and room ventilation.
Translate well, tap and sprinkler flow between L/min and gallons per minute.
GPM here is the US gallon per minute. Imperial GPM is about 20% larger; the imperial unit is shown separately.
1 GPM ≈ 3.785 L/min and 1 CFM ≈ 1.699 m³/h.
Multiply US gallons per minute by 3.785412. For example, 10 GPM ≈ 37.85 L/min.
Multiply CFM by 1.69901. For example, 500 CFM ≈ 849.5 m³/h.
One cubic meter per hour is about 0.27778 L/s.
Volumetric flow. To get mass flow, multiply by the fluid density (see the density converter).
