How to Convert Liters per Minute to GPH
To convert liters per minute to gph, multiply the flow rate by the following conversion ratio: 15.8503231 gph/liters per minute.
Since one liters per minute is equal to 15.8503231 gph, you can use this simple formula to convert:
The flow rate in gph is equal to the flow rate in liters per minute multiplied by 15.8503231.
For example, here's how to convert 5 liters per minute to gph using the formula above.
How Many GPH Are in a Liters per Minute?
There are 15.8503231 gph in a liters per minute, which is why we use this value in the formula above.
Our liters per minute to us gallons per hour 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 gph 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 Hour?
A us gallons per hour is a unit of flow rate equal to 0.0630902 liters per minute (L/min), the base unit for flow rate. Equal to 1/60 GPM (0.06309 L/min). [2]
The us gallons per hour is classified as a US customary unit of flow rate. GPH can be abbreviated as GPH; for example, 1 us gallons per hour can be written as 1 GPH.
When working with gph (GPH) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, gph (GPH) 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 gph (GPH), keep full floating-point precision (1 L/min = 15.8503231 GPH; 1 GPH = 0.0630902 L/min) during intermediate calculations and round only the final us gallons per hour figure to match your instrument tolerance.
