1. What is GPM to LPH Conversion?

The GPM to LPH 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:

Where:

• \( GPM \) — Flow rate in gallons per minute
• \( LPH \) — Flow rate in liters per hour
• \( 227.12470704 \) — Conversion factor (1 GPM = 227.12470704 LPH)

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

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for engineering design, process control, equipment specification, and international collaboration 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 (LPH).

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 227.12470704?
A: This factor combines volume conversion (1 gallon = 3.78541 liters) and time conversion (60 minutes = 1 hour): 3.78541 × 60 = 227.1246.

Q2: What are typical GPM values in practical applications?
A: Residential water flow: 2-5 GPM; industrial pumps: 10-1000 GPM; firefighting systems: 100-2000 GPM.

Q3: When is LPH preferred over GPM?
A: LPH is commonly used in metric system countries, scientific research, and international engineering standards.

Q4: How accurate is this conversion?
A: The conversion is mathematically exact based on standard definitions of gallon and liter.

Q5: Can this conversion be used for all fluids?
A: Yes, the conversion is valid for any fluid since it's purely a unit conversion, though density differences may affect mass flow rates.
