1. What is GPM to LPM Conversion?

GPM to LPM conversion is the process of converting flow rate measurements from gallons per minute to liters per minute. This conversion is essential in various fields including engineering, plumbing, irrigation, and fluid dynamics where different measurement systems are used.

2. How Does the Conversion Work?

The conversion uses the following formula:

Where:

• \( GPM \) — Flow rate in gallons per minute
• \( LPM \) — Flow rate in liters per minute
• \( 3.785411784 \) — Conversion factor (liters per gallon)

Explanation: One US gallon equals exactly 3.785411784 liters, so multiplying GPM by this factor gives the equivalent flow rate in liters per minute.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for international projects, equipment specifications, hydraulic calculations, and ensuring compatibility between systems using different measurement units.
