1. What is a LPS 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 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
• \( Q_{lps} \) — Flow rate in liters per second
• 15.850 — Conversion factor (1 L/s = 15.850 GPM)

Explanation: The conversion factor accounts for both volume (liters to gallons) and time (seconds to minutes) conversions.

3. Importance of Flow Rate Conversion

Details: Accurate conversion between units is essential for system design, pump selection, and compliance with different measurement standards.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 15.850?
A: It combines 1 liter = 0.264172 gallons and 1 second = 1/60 minutes (0.264172 × 60 = 15.850).

Q2: When would I need this conversion?
A: When working with international specifications, comparing pump ratings, or converting between metric and imperial systems.

Q3: How accurate is this conversion?
A: The conversion factor is precise to 6 decimal places (15.850323), but we use 15.850 for practical calculations.

Q4: Can I convert GPM back to L/s?
A: Yes, divide GPM by 15.850 to get L/s.

Q5: What's a typical L/s value for household plumbing?
A: Standard faucets typically flow at 0.1-0.2 L/s (1.6-3.2 GPM).
