How to Convert Liters per Hour to GPH
To convert liters per hour to gph, multiply the flow rate by the following conversion ratio: 0.2641721 gph/liters per hour.
Since one liters per hour is equal to 0.2641721 gph, you can use this simple formula to convert:
The flow rate in gph is equal to the flow rate in liters per hour multiplied by 0.2641721.
For example, here's how to convert 1000 liters per hour to gph using the formula above.
How Many GPH Are in a Liters per Hour?
There are 0.2641721 gph in a liters per hour, which is why we use this value in the formula above.
Our liters per hour 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 Hour and gph 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 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 hour (L/h) and gph (GPH), keep full floating-point precision (1 L/h = 0.2641721 GPH; 1 GPH = 3.7854118 L/h) during intermediate calculations and round only the final us gallons per hour figure to match your instrument tolerance.
