1. What is L/s to GPM Conversion?

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

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q_{gpm} \) — Flow rate in gallons per minute
• \( Q_{ls} \) — 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: Proper conversion ensures accurate system design, pump selection, and fluid dynamics calculations when working with international standards.

4. Using the Calculator

Tips: Enter the flow rate in liters per second. The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why convert between L/s and GPM?
A: Different countries use different measurement systems - metric (L/s) vs imperial (GPM).

Q2: How precise is the conversion factor?
A: The factor 15.850 is precise to 5 decimal places (actual value is 15.85032314).

Q3: When would I need this conversion?
A: When working with international equipment specifications, hydraulic calculations, or cross-border projects.

Q4: What's a typical flow rate in plumbing?
A: Residential faucets typically flow at 0.1-0.2 L/s (1.6-3.2 GPM).

Q5: Can I convert GPM back to L/s?
A: Yes, divide GPM by 15.850 to get L/s.
