Gallons Per Minute to LPM: A Comprehensive Guide for Flow Rate Conversion

In various industries, from plumbing to manufacturing, precise measurement and conversion of flow rates is crucial for efficient operations. One common conversion encountered is the transformation of gallons per minute (GPM) to liters per minute (LPM). This article provides a comprehensive guide to understanding and executing this conversion, including detailed formulas, conversion factors, tables, and practical applications.

Understanding Gallons Per Minute and Liters Per Minute

Gallons Per Minute (GPM):
A measure of volumetric flow rate representing the volume of liquid flowing through a pipe or channel per minute. It is commonly used in plumbing, firefighting, and irrigation systems.

Liters Per Minute (LPM):
A measure of volumetric flow rate representing the volume of liquid flowing through a pipe or channel per minute. It is widely used in many industries, including chemical processing, water treatment, and medical applications.

GPM to LPM Conversion Formula

The conversion between GPM and LPM is straightforward, utilizing the following formula:

LPM = GPM * 3.785

Alternatively, the following formula can be used for converting LPM to GPM:

GPM = LPM * 0.264

These conversion factors are derived from the conversion ratio of 1 gallon to 3.785 liters or 1 liter to 0.264 gallons.

Conversion Examples

To convert a flow rate of 10 GPM to LPM:

LPM = 10 GPM * 3.785 = 37.85 LPM

To convert a flow rate of 25 LPM to GPM:

GPM = 25 LPM * 0.264 = 6.6 GPM
