How to Convert GPD to Liters per Second
To convert gpd to liters per second, multiply the flow rate by the following conversion ratio: 0.000043813 liters per second/us gallons per day.
Since one us gallons per day is equal to 0.000043813 liters per second, you can use this simple formula to convert:
The flow rate in liters per second is equal to the flow rate in gpd multiplied by 0.000043813.
For example, here's how to convert 5 gpd to liters per second using the formula above.
How Many Liters per Second Are in a US Gallons per Day?
There are 0.000043813 liters per second in a us gallons per day, which is why we use this value in the formula above.
Our us gallons per day to liters per second calculator automatically converts your flow rate measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
GPD and liters per second are both units used to measure flow rate. Keep reading to learn more about each unit.
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. [1]
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.
What Is a Liters per Second?
A liters per second is a unit of flow rate equal to 60 liters per minute (L/min), the base unit for flow rate. Equal to 60 L/min. [2]
The liters per second is classified as a metric and SI-compatible unit of flow rate. Liters per Second can be abbreviated as L/s; for example, 1 liters per second can be written as 1 L/s.
When working with liters per second (L/s) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, liters per second (L/s) are widely used across standard flow rate applications within SI metric workflows, engineering documentation, and technical data sheets.
When converting flow rate between gpd (GPD) and liters per second (L/s), keep full floating-point precision (1 GPD = 0.000043813 L/s; 1 L/s = 22,824.4653237 GPD) during intermediate calculations and round only the final liters per second figure to match your instrument tolerance.
