1. What is US GPM to LPM Conversion?

The US GPM to LPM conversion is used to convert flow rate measurements from US gallons per minute to liters per minute. This conversion is essential in various fields including engineering, plumbing, irrigation, and fluid dynamics.

2. How Does the Conversion Work?

The conversion uses the following formula:

Where:

• \( LPM \) — Liters per minute
• \( US\ GPM \) — US gallons per minute
• \( 3.785411784 \) — Conversion factor (liters per US gallon)

Explanation: One US gallon is exactly equal to 3.785411784 liters, so multiplying the flow rate in US GPM by this conversion factor gives the equivalent flow rate in LPM.

3. Importance of Flow Rate Conversion

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

4. Using the Converter

Tips: Enter the flow rate in US gallons per minute. The value must be non-negative. The converter will automatically calculate the equivalent flow rate in liters per minute.
