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, and fluid dynamics where different measurement systems are used.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

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

Explanation: One US gallon equals exactly 3.785411784 liters, so multiplying US 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, and ensuring compatibility between systems using different measurement units. It's widely used in water treatment, chemical processing, and HVAC systems.

4. Using the Calculator

Tips: Enter the flow rate in US gallons per minute. The value must be non-negative. The calculator will instantly convert it to liters per minute with high precision.
