Do you need to convert liters per minute (LPM) to gallons per minute (GPM)? Whether you’re a professional in the water industry or a homeowner with a leaky faucet, this guide will help you make the conversion quickly and easily.

What is LPM?
Liters per minute (LPM) is a unit of measurement that expresses the volume of liquid flowing per minute. It is commonly used to measure the flow rate of water in pipes, pumps, and other plumbing fixtures.
What is GPM?
Gallons per minute (GPM) is another unit of measurement that expresses the volume of liquid flowing per minute. It is commonly used in the United States to measure the flow rate of water in plumbing systems, irrigation systems, and other applications.
Conversion Formula
To convert LPM to GPM, you can use the following formula:
GPM = LPM * 0.2642
For example, if you have a flow rate of 10 LPM, the equivalent flow rate in GPM would be:
GPM = 10 LPM * 0.2642 = 2.642 GPM
Table of Conversion Factors
The following table provides a quick reference for converting LPM to GPM:
LPM | GPM |
---|---|
1 | 0.2642 |
5 | 1.321 |
10 | 2.642 |
15 | 3.963 |
20 | 5.284 |
Common Mistakes to Avoid
When converting LPM to GPM, it is important to avoid the following mistakes:
- Using the wrong conversion factor: Make sure to use the correct conversion factor of 0.2642.
- Mixing units: Do not mix LPM and GPM in the same calculation.
- Rounding errors: Round the converted value to the nearest hundredth of a gallon per minute.
Applications of LPM and GPM Conversion
Converting LPM to GPM has a wide range of applications, including:
- Plumbing: Sizing pipes and pumps for water distribution systems.
- Irrigation: Determining the flow rate of water required for irrigation systems.
- Water treatment: Calculating the flow rate of water through water treatment plants.
- Hydraulics: Designing hydraulic systems for industrial and commercial applications.
Conclusion
Converting LPM to GPM is a straightforward process that can be easily performed using the formula provided in this guide. By understanding the difference between LPM and GPM and avoiding common mistakes, you can accurately convert flow rates for a variety of applications.
