GPM to Liters per Second: The Ultimate Conversion Guide

Understanding the Conversion

Gallons per minute (GPM) and liters per second (L/s) are two common units used to measure flow rates. GPM is typically used in the United States, while L/s is widely adopted in other parts of the world. Understanding the conversion between these units is crucial for various applications, such as hydraulics, plumbing, and water management.

Conversion Formula

The conversion formula from GPM to L/s is:

L/s = GPM * 0.06309

Alternatively, you can convert from L/s to GPM using the following formula:

gpm to litres per second

GPM = L/s * 15.85

Examples

To convert 5 GPM to L/s, use:

L/s = 5 GPM * 0.06309 = 0.315 L/s

To convert 20 L/s to GPM, use:

GPM = 20 L/s * 15.85 = 317 GPM

Applications of GPM to L/s Conversion

The conversion between GPM and L/s finds applications in numerous fields:

1. Hydraulics: In hydraulic systems, pumps, valves, and actuators are designed to operate within specific flow rate ranges. Converting between GPM and L/s ensures compatibility between components and accurate system design.

2. Plumbing: Whether it's residential or commercial plumbing, knowing the conversion allows installers and engineers to size pipes, pumps, and fixtures appropriately to meet specific flow requirements.
