1. What is GPM to L/min Converter?

Definition: This calculator converts flow rate from gallons per minute (GPM) to liters per minute (L/min).

Purpose: It helps engineers, technicians, and professionals working with fluid systems to convert between imperial and metric flow rate units.

2. How Does the Converter Work?

The converter uses the formula:

\[ Q_{lpm} = Q_{gpm} \times 3.785 \]

Where:

\( Q_{lpm} \) — Flow rate in liters per minute (L/min)
\( Q_{gpm} \) — Flow rate in gallons per minute (GPM)
3.785 — Conversion factor (1 gallon = 3.785 liters)

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is essential for system design, pump selection, and process control in international projects where different unit systems are used.

4. Using the Converter

Tips: Simply enter the flow rate in gallons per minute (GPM) and the calculator will automatically compute the equivalent in liters per minute (L/min).

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 3.785?
A: This is because 1 US gallon is exactly equal to 3.785411784 liters.

Q2: Does this work for both US and UK gallons?
A: No, this converter uses US gallons (1 US gal = 3.785 L). UK gallons are different (1 UK gal = 4.546 L).

Q3: How precise is this conversion?
A: The conversion is mathematically exact. The precision of your result depends on the precision of your input value.

Q4: Can I convert L/min back to GPM?
A: Yes, you would divide the L/min value by 3.785 to get GPM.

Q5: Where is this conversion commonly used?
A: This is frequently used in hydraulic systems, water treatment, irrigation, and any fluid mechanics applications.
