1. What is a L/s to GPM Calculator?

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

Purpose: It helps engineers, plumbers, and technicians 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 (GPM)
• \( Q_{ls} \) — Flow rate in liters per second (L/s)
• 15.850 — Conversion factor (1 L/s = 15.850 GPM)

Explanation: The conversion factor accounts for both volume conversion (1 liter = 0.264172 gallons) and time conversion (1 second = 1/60 minute).

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is essential for system design, pump selection, and ensuring compatibility between metric and imperial measurement systems.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 15.850?
A: It combines volume conversion (1 L = 0.264172 gal) and time conversion (60 seconds/minute): 0.264172 × 60 = 15.850.

Q2: When would I need this conversion?
A: When working with international specifications, equipment with different unit systems, or when comparing flow rates from different sources.

Q3: How accurate is this conversion?
A: The conversion is mathematically exact, though real-world measurements may have instrumentation errors.

Q4: Can I convert GPM back to L/s?
A: Yes, divide GPM by 15.850 or use our GPM to L/s calculator.

Q5: What's a typical flow rate in plumbing?
A: Residential faucets typically flow at 0.1-0.2 L/s (1.5-3 GPM), while shower heads might be 0.08-0.16 L/s (1.2-2.5 GPM).
