The GPM to LPM conversion is used to convert flow rate measurements from 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:

• \( LPM \) — Liters per minute
• \( GPM \) — Gallons per minute
• \( 3.785411784 \) — Conversion factor (1 gallon = 3.785411784 liters)

Explanation: The conversion factor is derived from the exact definition of US liquid gallon, which equals exactly 3.785411784 liters.

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 standards. It's widely used in water treatment, irrigation systems, and industrial processes.

4. Using the Calculator

Tips: Enter the flow rate in gallons per minute (GPM). The value must be positive. The calculator will automatically convert it to liters per minute (LPM) with high precision.

5. Frequently Asked Questions (FAQ)

Q1: What is the exact conversion factor?
A: The exact conversion factor is 3.785411784, which represents the number of liters in one US liquid gallon.

Q2: Is this conversion for US gallons or imperial gallons?
