1. What is GPM to L/hr Conversion?

The GPM to L/hr conversion calculates flow rate 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:

\[ L/hr = GPM \times 227.12470704 \]

Where:

\( GPM \) — Flow rate in gallons per minute
\( L/hr \) — Flow rate in liters per hour
\( 227.12470704 \) — Conversion factor (1 GPM = 227.12470704 L/hr)

Explanation: The conversion factor accounts for both volume conversion (1 gallon = 3.78541 liters) and time conversion (1 minute to 60 minutes/hour).

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for international engineering projects, fluid system design, chemical processing, and water treatment facilities where different measurement systems are used.

4. Using the Calculator

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

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) by 60 (minutes to hours): 3.785411784 × 60 = 227.12470704.

Q2: What are common applications for this conversion?
A: Used in plumbing, irrigation systems, chemical processing, fuel flow measurements, and any application involving liquid flow rates between US customary and metric systems.

Q3: How accurate is this conversion?
A: The conversion uses standard definitions and is mathematically exact. Accuracy depends on the precision of your input measurement.

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

Q5: Are there different types of gallons?
A: This calculator uses US gallons. Imperial gallons are different (1 imperial gallon = 4.54609 liters), so the conversion factor would be different for imperial measurements.
