1. What is US GPM to LPM Converter?

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

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

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion ensures proper system design, equipment selection, and performance calculations in hydraulic systems, plumbing, and industrial processes.

4. Using the Converter

Tips: Simply enter the flow rate in US GPM and the converter will automatically calculate the equivalent in LPM.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between US gallon and imperial gallon?
A: 1 US gallon = 3.785 liters, while 1 imperial gallon = 4.546 liters. This converter uses US gallons.

Q2: When would I need this conversion?
A: When working with international specifications, metric equipment, or when comparing systems using different measurement standards.

Q3: Is the conversion factor exact?
