1. What is GPM to LPM Conversion?

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

Purpose: It helps engineers, plumbers, and technicians work with flow rate measurements in different unit systems.

2. How Does the Calculator Work?

The calculator 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)

Explanation: The GPM value is multiplied by 3.785 to convert to LPM.

3. Importance of Flow Rate Conversion

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

4. Using the Calculator

Tips: Enter the flow rate in US gallons per minute (GPM). The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why convert GPM to LPM?
A: Many countries use metric system (LPM) while some equipment uses US customary units (GPM). Conversion ensures proper system design and operation.

Q2: Is this for US gallons or UK gallons?
A: 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, comparing pump performance, or designing fluid systems.

Q4: How precise is this conversion?
A: The conversion factor (3.785) provides precision to three decimal places, sufficient for most engineering applications.

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