1. What is GPM to LPH Conversion?

GPM to LPH conversion is used to convert flow rates from gallons per minute to liters per hour. This conversion is essential in various engineering, industrial, and scientific applications where fluid flow measurements need to be standardized across different unit systems.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( LPH \) — Liters per hour
• \( GPM \) — Gallons per minute
• \( 227.12470704 \) — Conversion factor (exact value)

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

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for international engineering projects, fluid system design, pump specifications, and ensuring compatibility between equipment using different measurement systems.

4. Using the Calculator

Tips: Enter the flow rate in gallons per minute (GPM). The value must be non-negative. The calculator will automatically compute the equivalent flow rate in liters per hour (LPH).

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 227.12470704?
A: This factor comes from multiplying the gallon-to-liter conversion (3.785411784 liters/gallon) by the minutes-to-hours conversion (60 minutes/hour).

Q2: What are common applications for GPM to LPH conversion?
A: Water treatment plants, irrigation systems, fuel flow measurements, chemical processing, and HVAC systems often require this conversion.

Q3: Is this conversion exact?
A: Yes, the conversion factor is mathematically exact based on standard definitions of gallons and liters.

Q4: Can I convert LPH back to GPM?
A: Yes, use the inverse formula: GPM = LPH ÷ 227.12470704.

Q5: What's the difference between US gallon and imperial gallon?
A: This calculator uses US gallons (3.785 liters). Imperial gallons are larger (4.546 liters) and would require a different conversion factor.
