1. What is a GPM to LPM Converter?

Definition: This tool converts flow rate measurements from gallons per minute (GPM) to liters per minute (LPM).

Purpose: It helps engineers, technicians, and professionals working with fluid systems to easily convert between these common 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 (LPM)
\( Q_{gpm} \) — Flow rate in gallons per minute (GPM)
3.785 — Conversion factor (1 gallon = 3.785 liters)

Explanation: The conversion is straightforward as it's based on the fixed relationship between gallons and liters.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is essential for system design, equipment specification, and international collaboration where different measurement systems are used.

4. Using the Converter

Tips: Simply enter the flow rate in GPM and the converter will automatically calculate the equivalent in LPM. The value must be ≥ 0.

5. Frequently Asked Questions (FAQ)

Q1: Why convert between GPM and LPM?
A: GPM is commonly used in the US, while LPM is standard in metric countries. Conversion is needed for international projects and equipment compatibility.

Q2: Is the conversion factor exact?
A: Yes, 1 US gallon is exactly 3.785411784 liters, though we use 3.785 for practical calculations.

Q3: Does this work for imperial gallons?
A: No, this converter uses US gallons. Imperial gallons (UK) use a different conversion factor (1 imperial gallon = 4.54609 liters).

Q4: What are typical applications?
A: Used in water systems, hydraulic systems, fuel flow measurements, and any application involving liquid flow rates.

Q5: Can I convert LPM back to GPM?
A: Yes, simply divide LPM by 3.785 to get GPM. We may add a reverse converter in future updates.
