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 is essential for engineering, plumbing, and fluid dynamics applications where different measurement systems are used.

2. How Does the Conversion Work?

The conversion uses the formula:

Where:

• \( L/s \) — Flow rate in liters per second
• \( GPM \) — Flow rate in gallons per minute
• \( 15.850323141488905 \) — Conversion factor (exact value)

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

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for international projects, equipment specification, hydraulic calculations, and ensuring compatibility between systems using different measurement standards.

4. Using the Converter

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

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor so precise?
A: The factor 15.850323141488905 is exact and derived from the definitions: 1 gallon = 3.785411784 liters and 1 minute = 60 seconds.

Q2: When is this conversion typically used?
A: Commonly used in water supply systems, irrigation, industrial processes, fire protection systems, and any application involving fluid flow measurements.

Q3: What's the difference between US gallon and imperial gallon?
A: This converter uses US gallons (3.785 liters). Imperial gallons are larger (4.546 liters) and would require a different conversion factor.

Q4: Can I convert GPM back to L/s?
A: Yes, use the inverse: L/s = GPM ÷ 15.850323141488905 or L/s = GPM × 0.06309.

Q5: What are typical flow rate ranges?
A: Residential faucets: 0.1-0.3 L/s (1.5-4.5 GPM), shower heads: 0.16 L/s (2.5 GPM), garden hoses: 0.3-0.6 L/s (5-10 GPM).
