How to Convert GPM to GPD
To convert gpm to gpd, multiply the flow rate by the following conversion ratio: 1,440 gpd/us gallons per minute.
Since one us gallons per minute is equal to 1,440 gpd, you can use this simple formula to convert:
The flow rate in gpd is equal to the flow rate in gpm multiplied by 1,440.
For example, here's how to convert 5 gpm to gpd using the formula above.
How Many GPD Are in a US Gallons per Minute?
There are 1,440 gpd in a us gallons per minute, which is why we use this value in the formula above.
Our us gallons per minute 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.
GPM and gpd are both units used to measure flow rate. Keep reading to learn more about each unit.
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). [1]
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.
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 gpm (GPM) and gpd (GPD), keep full floating-point precision (1 GPM = 1,440 GPD; 1 GPD = 0.000694444 GPM) during intermediate calculations and round only the final us gallons per day figure to match your instrument tolerance.
