How to Convert Liter per Minute to Gallon per Minute
- 1 L/min = 0.2641720524 GPM
- 1 GPM = 3.785411784 L/min
- Example: convert 15 L/min to GPM: 15 L/min = 15 × 0.2641720524 GPM = 3.962580785 GPM
Formula
GPM = L/min × 0.2641720523581
or GPM = L/min ÷ 3.785411784
Derivation from SI units:
- 1 L/min = 10⁻³ m³ ÷ 60 s
- 1 GPM = 231 in³ ÷ 60 s = 0.003785411784 m³ ÷ 60 s = 6.30901964 × 10⁻⁵ m³/s
- 1 L/min = 0.00001666666666667 m³/s ÷ 0.0000630901964 m³/s per GPM = 0.2641720523581 GPM
Both units are defined exactly, so the factor is exact. Liter per Minute definition: liter per minute; Gallon per Minute definition: US gallon per minute.
Worked examples
- A kitchen tap flow of 10 L/min is 2.641720524 GPM.
10 L/min × 0.2641720524 = 2.641720524 GPM - A 60 L/min pump delivers 15.85032314 GPM.
60 L/min × 0.2641720524 = 15.85032314 GPM

Frequently asked questions
Does GPM mean US or imperial gallons here?
US gallons. For imperial gallons per minute, 1 L/min = 0.21997 imp gal/min.
How many US gallons per minute are in 1 liter per minute?
1 L/min = 0.2641720524 GPM.
How do I convert liters per minute to US gallons per minute?
Multiply the value in L/min by 0.2641720524, or divide it by 3.785411784. For example, 15 L/min × 0.2641720524 = 3.962580785 GPM.
Is the L/min to GPM conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
