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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: Since 1 US gallon equals 3.785 liters, we multiply the GPM value by 3.785 to get the equivalent flow rate in LPM.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is essential for system design, pump sizing, and when working with equipment specifications that use different measurement systems.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Is this conversion for US gallons or UK gallons?
A: This calculator uses US gallons (1 US gallon = 3.785 liters). UK gallons are different (1 UK gallon = 4.546 liters).

Q2: When would I need to convert GPM to LPM?
A: When working with international equipment specifications, metric system requirements, or comparing systems using different measurement units.

Q3: How precise is this conversion?
A: The conversion factor 3.785 is precise enough for most engineering applications. For higher precision, use 3.785411784.

Q4: Can I convert LPM back to GPM?
A: Yes, divide LPM by 3.785 to get GPM. We may add a reverse calculator in the future.

Q5: Does this work for any liquid or just water?
A: This converts volume flow rate units only. The liquid density doesn't affect the volume conversion.
