How to Convert Liters per Hour to GPD
To convert liters per hour to gpd, multiply the flow rate by the following conversion ratio: 6.3401293 gpd/liters per hour.
Since one liters per hour is equal to 6.3401293 gpd, you can use this simple formula to convert:
The flow rate in gpd is equal to the flow rate in liters per hour multiplied by 6.3401293.
For example, here's how to convert 5 liters per hour to gpd using the formula above.
How Many GPD Are in a Liters per Hour?
There are 6.3401293 gpd in a liters per hour, which is why we use this value in the formula above.
Our liters per hour to us gallons per day calculator automatically converts your flow rate measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

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 Day?
A us gallons per day is a unit of flow rate equal to 0.0026288 liters per minute (L/min), the base unit for flow rate. Water treatment flow unit. [2]
The us gallons per day is classified as a US customary unit of flow rate. GPD can be abbreviated as GPD; for example, 1 us gallons per day can be written as 1 GPD.
When working with gpd (GPD) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, gpd (GPD) are widely used across fine-tolerance laboratory, analytical, and micro-scale flow rate measurements within US customary workflows, engineering documentation, and technical data sheets.
When converting flow rate between liters per hour (L/h) and gpd (GPD), keep full floating-point precision (1 L/h = 6.3401293 GPD; 1 GPD = 0.1577255 L/h) during intermediate calculations and round only the final us gallons per day figure to match your instrument tolerance.
