1. What is USGPM to LPM Conversion?

Definition: This calculator converts flow rate from US Gallons Per Minute (GPM) to Liters Per Minute (LPM).

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

2. How Does the Conversion Work?

The calculator uses the formula:

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

Where:

\( Q_{lpm} \) — Flow rate in liters per minute
\( Q_{gpm} \) — Flow rate in US gallons per minute
3.785 — Conversion factor (1 US gallon = 3.78541 liters)

3. Importance of Flow Rate Conversion

Details: Accurate conversion between units is essential for system design, pump sizing, and international collaboration where different measurement systems are used.

4. Using the Calculator

Tips: Simply enter the flow rate in US gallons per minute (GPM) and the calculator will instantly provide the equivalent in liters per minute (LPM).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between US gallon and Imperial gallon?
A: A US gallon is 3.785 liters, while an Imperial gallon is 4.546 liters. This calculator uses US gallons.

Q2: How precise is the conversion factor?
A: The exact conversion is 1 US gallon = 3.785411784 liters, but we use 3.785 for most practical applications.

Q3: When would I need to convert GPM to LPM?
A: When working with international equipment specifications, metric system requirements, or comparing data from different sources.

Q4: Can I convert LPM back to GPM with this calculator?
A: No, this is a one-way conversion. For reverse conversion, divide LPM by 3.785.

Q5: Is this conversion valid for all liquids?
A: Yes, the conversion is based on volume, so it works for any liquid, though the mass flow rate would differ based on density.
