1. What is GPM to L/min Conversion?

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, and fluid dynamics where different measurement systems are used.

2. How Does the Conversion Work?

The conversion uses the formula:

Where:

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

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, and ensuring compatibility between systems using different measurement units. It's widely used in water treatment, HVAC systems, and industrial processes.

4. Using the Converter

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

5. Frequently Asked Questions (FAQ)

Q1: What is the exact conversion factor?
A: The exact conversion factor is 3.785411784 liters per US gallon.

Q2: Does this conversion work for imperial gallons?
A: No, this conversion is for US gallons. Imperial gallons are larger (1 imperial gallon = 4.54609 liters).

Q3: Where is this conversion commonly used?
A: Commonly used in water flow measurements, pump specifications, irrigation systems, and fluid dynamics calculations.

Q4: How accurate is this conversion?
A: The conversion is mathematically exact based on the defined relationship between US gallons and liters.

Q5: Can I convert L/min back to GPM?
A: Yes, to convert back, divide L/min by 3.785411784 to get GPM.
