1. What is GPM to L/M Conversion?

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

Purpose: It helps engineers, plumbers, and technicians work with different measurement systems in fluid dynamics applications.

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)

3. Importance of Flow Rate Conversion

Details: Accurate conversion between measurement systems ensures proper system design, equipment selection, and performance evaluation.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why convert GPM to L/M?
A: Many countries use metric system (L/M) while some equipment specifications use GPM. Conversion ensures compatibility.

Q2: Is 3.785 always the conversion factor?
A: Yes, 1 US gallon is exactly 3.785411784 liters. We use 3.785 for practical calculations.

Q3: What's a typical GPM value for household plumbing?
A: Standard faucets flow about 1-2 GPM (3.8-7.6 L/M), while showerheads typically use 2.5 GPM (9.5 L/M).

Q4: Can I convert L/M back to GPM?
A: Yes, divide L/M by 3.785 to get GPM. We may add this reverse calculator in future.

Q5: Does this work for other time periods?
A: The conversion factor remains the same regardless of time unit (per minute, per hour, etc.).
