1. What is LPM to GPM Conversion?

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

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: Since 1 gallon equals approximately 3.785 liters, we divide the LPM value by 3.785 to get GPM.

3. Importance of Flow Rate Conversion

Details: Accurate conversion between measurement systems is crucial for international projects, equipment specifications, and system design.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 3.785?
A: This is because 1 US gallon is exactly equal to 3.785411784 liters.

Q2: Is this conversion different for UK gallons?
A: Yes, for UK gallons use 4.546 as the conversion factor instead of 3.785.

Q3: What are common applications for this conversion?
A: Used in hydraulic systems, water treatment, irrigation, and any fluid flow measurement.

Q4: How precise is this conversion?
A: The calculator provides results to 3 decimal places, suitable for most engineering applications.

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