1. What is L/S to GPM Conversion?

The L/S to GPM conversion calculates flow rate from liters per second to gallons per minute. This conversion is essential in fluid dynamics, plumbing, irrigation systems, and various engineering applications where flow rates need to be converted between metric and imperial units.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( Q_{gpm} \) — Flow rate in gallons per minute
• \( Q_{ls} \) — Flow rate in liters per second
• 15.85 — Conversion factor (1 L/s = 15.85 GPM)

Explanation: The conversion factor 15.85 is derived from the relationship between liters and gallons (1 gallon = 3.78541 liters) and seconds to minutes (1 minute = 60 seconds).

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for international engineering projects, equipment specification, pump selection, and system design where different measurement systems are used.

4. Using the Calculator

Tips: Enter the flow rate in liters per second (L/s). The value must be non-negative. The calculator will automatically convert it to gallons per minute (GPM).

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 15.85?
A: The factor comes from: 1 L/s = (1/3.78541) gal/s × 60 s/min = 15.8503 ≈ 15.85 GPM.

Q2: What are typical flow rates in L/s and GPM?
A: Household faucet: 0.1-0.2 L/s (1.6-3.2 GPM), Shower: 0.2-0.3 L/s (3.2-4.8 GPM), Garden hose: 0.3-0.6 L/s (4.8-9.5 GPM).

Q3: When is this conversion needed?
A: When working with international standards, comparing pump specifications, designing plumbing systems, or converting between metric and imperial units in fluid mechanics.

Q4: Are there limitations to this conversion?
A: The conversion is mathematically exact for pure water. For other fluids, density variations may require additional considerations.

Q5: Can I convert GPM back to L/s?
A: Yes, use the inverse: Q_ls = Q_gpm ÷ 15.85 or Q_ls = Q_gpm × 0.0631.
