1. What is LPH to GPM Conversion?

Definition: This calculator converts flow rate from liters per hour (LPH) to gallons per minute (GPM).

Purpose: It helps in fluid dynamics calculations, especially when working with different measurement systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q_{gpm} \) — Flow rate in gallons per minute
• \( Q_{lph} \) — Flow rate in liters per hour
• 3.785 — Liters in one gallon
• 60 — Minutes in one hour

Explanation: The formula converts liters to gallons and hours to minutes to get the equivalent flow rate.

3. Importance of Flow Rate Conversion

Details: Accurate conversion between measurement systems is crucial in engineering, plumbing, and fluid system design.

4. Using the Calculator

Tips: Enter the flow rate in liters per hour (LPH). The value must be ≥ 0.

5. Frequently Asked Questions (FAQ)

Q1: Why convert between LPH and GPM?
A: Different countries and industries use different measurement systems, and conversions are often needed for compatibility.

Q2: How accurate is this conversion?
A: The conversion is mathematically precise, using the standard definition of 1 gallon = 3.785 liters.

Q3: When would I need this conversion?
A: Common applications include plumbing design, chemical processing, and irrigation system planning.

Q4: Can I convert GPM back to LPH?
A: Yes, use the inverse formula: \( Q_{lph} = Q_{gpm} \times 3.785 \times 60 \).

Q5: Why show 6 decimal places?
A: For precision in engineering calculations, though you can round as needed for your application.
