Converting liters per minute (L/min) to gallons per minute (GPM) is a crucial calculation in various industries, including water management, chemical processing, and automotive engineering. This comprehensive guide will provide you with all the essential information and tools you need to accurately perform this conversion.

Understanding L/min and GPM
- Liters per minute (L/min) measures the volume of fluid flowing past a specific point in a minute. It is commonly used in Europe and other regions of the world.
- Gallons per minute (GPM) measures the volume of fluid flowing past a specific point in a minute. It is the standard unit of flow rate in the United States and Canada.
Conversion Formula
The conversion formula for L/min to GPM is:
GPM = L/min × 0.264172
Example:
If you have a flow rate of 100 L/min, you can convert it to GPM as follows:
GPM = 100 L/min × 0.264172 = 26.4172 GPM
Conversion Table
For your convenience, here is a table that provides conversions for common flow rates:
L/min | GPM |
---|---|
1 | 0.264 |
5 | 1.32 |
10 | 2.64 |
20 | 5.28 |
50 | 13.21 |
100 | 26.42 |
200 | 52.84 |
500 | 132.09 |
1000 | 264.18 |
