1. What is GPM to L/s Converter?

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

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

2. How Does the Converter Work?

The converter uses the formula:

Where:

• \( Q_{ls} \) — Flow rate in liters per second (L/s)
• \( Q_{gpm} \) — Flow rate in gallons per minute (GPM)
• 15.850 — Conversion factor (1 GPM = 0.06309 L/s)

Explanation: The conversion factor is derived from the relationship between gallons and liters (1 gallon = 3.78541 liters) and minutes to seconds (1 minute = 60 seconds).

3. Importance of Flow Rate Conversion

Details: Converting between GPM and L/s is essential when working with international standards, equipment specifications, or when comparing systems using different measurement units.

4. Using the Converter

Tips: Simply enter the flow rate in GPM and the calculator will instantly provide the equivalent in L/s.

5. Frequently Asked Questions (FAQ)

Q1: Why convert GPM to L/s?
A: Many international standards and scientific calculations use metric units (L/s), while some equipment still uses imperial units (GPM).

Q2: How precise is this conversion?
A: The conversion factor (15.850) provides precision to 5 decimal places (0.06309 L/s per GPM).

Q3: What's a typical flow rate in plumbing?
A: Residential faucets typically flow at 1-2 GPM (0.063-0.126 L/s), while shower heads are about 2.5 GPM (0.158 L/s).

Q4: Can I convert L/s back to GPM?
A: Yes, multiply L/s by 15.850 to get GPM (inverse of our formula).

Q5: Where is this conversion most used?
A: Common in water supply systems, HVAC, fire protection, and industrial fluid systems.
