1. What is GPM to L/min Conversion?

The GPM to L/min conversion is used to convert flow rate measurements from gallons per minute (GPM) to liters per minute (L/min). This conversion is essential in various fields including engineering, plumbing, hydraulics, and fluid dynamics where different measurement systems are used.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( GPM \) — Flow rate in gallons per minute
• \( 3.785411784 \) — Conversion factor (1 gallon = 3.785411784 liters)
• \( L/min \) — Resulting flow rate in liters per minute

Explanation: The conversion factor is derived from the exact definition of 1 US gallon equals 3.785411784 liters.

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.

4. Using the Calculator

Tips: Enter the flow rate in gallons per minute (GPM). The value must be non-negative. The calculator will instantly convert it to liters per minute (L/min).

5. Frequently Asked Questions (FAQ)
