1. What is GPM to LPM Conversion?

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

Purpose: It helps in fluid dynamics calculations, especially when working with international standards or equipment specifications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The conversion is a simple multiplication since 1 US gallon equals exactly 3.785411784 liters.

3. Importance of Flow Rate Conversion

Details: Accurate conversion between units is essential for proper system design, pump selection, and compliance with international standards.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Is this conversion exact?
A: Yes, the conversion factor 3.785 is based on the exact definition of 1 US gallon = 3.785411784 liters.

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

Q3: When would I need this conversion?
A: When working with international equipment specifications, metric system requirements, or scientific calculations.

Q4: What's a typical GPM value for household water?
A: Standard household faucets typically deliver 1-2 GPM (3.8-7.6 LPM), while showerheads are often 2.5 GPM (9.5 LPM).

Q5: Can I convert LPM back to GPM?
A: Yes, simply divide the LPM value by 3.785 to get GPM.
