1. What is LPS to GPM Conversion?

LPS to GPM conversion is used to convert flow rates from liters per second (LPS) to gallons per minute (GPM). This conversion is essential in various engineering fields, particularly in fluid dynamics, plumbing, and irrigation systems where different measurement units are used.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( Q_{gpm} \) — Flow rate in gallons per minute
• \( Q_{lps} \) — Flow rate in liters per second
• 15.850 — Conversion factor from LPS to GPM

Explanation: The conversion factor 15.850 is derived from the relationship between liters and gallons (1 gallon = 3.78541 liters) and the time conversion between seconds and minutes (1 minute = 60 seconds).

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for international engineering projects, equipment specification, system design, and ensuring compatibility between components that use different measurement systems.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is the exact conversion factor?
A: The exact conversion factor is 15.850323, which is rounded to 15.850 for practical calculations.

Q2: When is this conversion typically used?
A: This conversion is commonly used in water supply systems, hydraulic engineering, fire protection systems, and industrial processes.

Q3: Are there different types of gallons?
A: Yes, this calculator uses US gallons. Imperial gallons (UK) have a different conversion factor (1 imperial gallon = 4.54609 liters).

Q4: How accurate is this conversion?
A: The conversion is accurate for most engineering applications. For precise scientific calculations, use the exact conversion factor.

Q5: Can I convert GPM back to LPS?
A: Yes, to convert GPM to LPS, divide the GPM value by 15.850 (or multiply by 0.06309).
