GPM to liters per minute
1 US GPM = 3.785411784 L/min.
Convert known volumetric flow rates among metric and US customary units, including L/min, US GPM, CFM, and m³/h.
Volumetric flow rate describes a volume of fluid passing a point per unit time. Common units include liters per minute, cubic meters per hour, US gallons per minute, and cubic feet per minute.
This converter changes the unit of an already-known flow rate. It does not calculate total usage, size pipes or pumps, determine pressure loss, or convert volume flow directly to mass flow.
Every conversion passes through cubic meters per second without pairwise formulas.

10 L/min ÷ 3.785411784 ≈ 2.6417205236 US GPM.
1 CFM = 28.316846592 L/min.
100 CFM = 169.901079552 m³/h.
5 m³/h × 1,000 ÷ 60 ≈ 83.3333333333 L/min.
2 L/s ≈ 31.700646283 US GPM.
3.785411784 L/min or 0.22712470704 m³/h.
Approximately 0.2641720524 US GPM.
28.316846592 L/min, approximately 7.4805194805 US GPM.
Approximately 16.6666666667 L/min.
60 L/min, approximately 15.8503231415 US GPM.
L/min is a metric flow unit. One liter is exactly 0.001 cubic meter, and one minute is exactly 60 seconds.
GPM on this page always means US gallons per minute. One US gallon is exactly 3.785411784 liters. Imperial gallons are not included, avoiding an ambiguous unlabeled gallon conversion.
CFM means cubic feet per minute and is commonly used for airflow and ventilation. This converter changes CFM units only; it does not determine required HVAC airflow.
m³/h is widely used for larger liquid and gas flow rates. One m³/h equals 1,000 liters per hour, or approximately 16.6666666667 L/min.
Volume is an amount such as liters or gallons. Flow rate includes a time denominator. Converting 5 GPM to L/min does not determine total consumption without a duration; use the Water Usage Calculator for flow multiplied by time and recurrence.
Volume flow uses units such as L/min and m³/s. Mass flow uses units such as kg/s and lb/h. Converting between them requires fluid density, which this converter does not assume.
A negative value can represent direction relative to a defined axis or measurement convention. Unit conversion preserves the sign without interpreting the physical system.
Multiply by the source unit's factor to m³/s, then divide by the target unit's factor to m³/s.
It is the volume passing a point per unit time.
The coherent SI unit is the cubic meter per second, m³/s.
One US GPM equals exactly 3.785411784 L/min.
One L/min is approximately 0.2641720524 US GPM.
Multiply US GPM by 0.22712470704.
Divide m³/h by 0.22712470704.
One CFM equals exactly 28.316846592 L/min under the exact international-foot definition.
Multiply CFM by 1.69901079552.
GPM means US gallons per minute on this calculator.
CFM means cubic feet per minute.
GPM on this page uses the US gallon. Imperial-gallon units are not included.
No. Volume is an amount; flow rate is volume per unit time.
No. Total usage additionally depends on how long and how often the flow occurs.
No. That requires the fluid's density, which is not assumed here.
Volume flow measures volume per time, while mass flow measures mass per time.
