How to Convert Liters per Minute to GPM
To convert liters per minute to gpm, multiply the flow rate by the following conversion ratio: 0.2641721 gpm/liters per minute.
Since one liters per minute is equal to 0.2641721 gpm, you can use this simple formula to convert:
The flow rate in gpm is equal to the flow rate in liters per minute multiplied by 0.2641721.
For example, here's how to convert 20 liters per minute to gpm using the formula above.
How Many GPM Are in a Liters per Minute?
There are 0.2641721 gpm in a liters per minute, which is why we use this value in the formula above.
Our liters per minute to us gallons per minute calculator automatically converts your flow rate measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Liters per Minute and gpm are both units used to measure flow rate. Keep reading to learn more about each unit.
What Is a Liters per Minute?
Volumetric flow of 1 liter per minute. It serves as a primary reference unit for measuring flow rate across scientific and practical applications. [1]
The liters per minute is classified as a metric and SI-compatible unit of flow rate. Liters per Minute can be abbreviated as L/min; for example, 1 liters per minute can be written as 1 L/min.
As the primary coherent reference unit for flow rate in this category, all other flow rate units are mathematically anchored to the liters per minute (L/min).
In practice, liters per minute (L/min) are widely used across standard flow rate applications within SI metric workflows, engineering documentation, and technical data sheets.
What Is a US Gallons per Minute?
A us gallons per minute is a unit of flow rate equal to 3.7854118 liters per minute (L/min), the base unit for flow rate. Standard US plumbing & pump flow rate (3.78541 L/min). [2]
The us gallons per minute is classified as a US customary unit of flow rate. GPM can be abbreviated as GPM; for example, 1 us gallons per minute can be written as 1 GPM.
When working with gpm (GPM) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, gpm (GPM) are widely used across standard flow rate applications within US customary workflows, engineering documentation, and technical data sheets.
When converting flow rate between liters per minute (L/min) and gpm (GPM), keep full floating-point precision (1 L/min = 0.2641721 GPM; 1 GPM = 3.7854118 L/min) during intermediate calculations and round only the final us gallons per minute figure to match your instrument tolerance.
