How to Convert Liters per Hour to GPM
To convert liters per hour to gpm, multiply the flow rate by the following conversion ratio: 0.0044029 gpm/liters per hour.
Since one liters per hour is equal to 0.0044029 gpm, you can use this simple formula to convert:
The flow rate in gpm is equal to the flow rate in liters per hour multiplied by 0.0044029.
For example, here's how to convert 5 liters per hour to gpm using the formula above.
How Many GPM Are in a Liters per Hour?
There are 0.0044029 gpm in a liters per hour, which is why we use this value in the formula above.
Our liters per hour 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 Hour and gpm are both units used to measure flow rate. Keep reading to learn more about each unit.
What Is a Liters per Hour?
A liters per hour is a unit of flow rate equal to 1/60 of a liters per minute (0.0166667 L/min). Equal to 1/60 L/min. [1]
The liters per hour is classified as a metric and SI-compatible unit of flow rate. Liters per Hour can be abbreviated as L/h; for example, 1 liters per hour can be written as 1 L/h.
When working with liters per hour (L/h) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, liters per hour (L/h) 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 hour (L/h) and gpm (GPM), keep full floating-point precision (1 L/h = 0.0044029 GPM; 1 GPM = 227.124707 L/h) during intermediate calculations and round only the final us gallons per minute figure to match your instrument tolerance.
