1. What is Liters Per Hour to GPM Conversion?

The conversion from liters per hour (LPH) to gallons per minute (GPM) is a common unit conversion used in fluid dynamics, engineering, and various industrial applications to convert flow rates between metric and imperial systems.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( GPM \) — Gallons per minute (imperial flow rate)
• \( LPH \) — Liters per hour (metric flow rate)
• \( 227.12470704 \) — Conversion factor (liters per hour to gallons per minute)

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

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is essential in international engineering projects, fluid system design, pump specifications, and when working with equipment that uses different measurement systems.

4. Using the Calculator

Tips: Enter the flow rate in liters per hour (LPH). The value must be positive. 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 precise conversion factor is 227.12470704, which comes from 1 gallon = 3.785411784 liters and 1 hour = 60 minutes.

Q2: Is this US gallons or imperial gallons?
A: This conversion uses US gallons (1 US gallon = 3.785411784 liters). Imperial gallons are different (1 imperial gallon = 4.54609 liters).

Q3: When is this conversion commonly used?
A: Commonly used in automotive fuel systems, industrial fluid transfer, irrigation systems, and any application where flow rates need to be converted between metric and US customary units.

Q4: How accurate is this conversion?
A: The conversion is mathematically exact based on standard definitions of liters and gallons. The calculator provides results with 6 decimal places for precision.

Q5: Can I convert GPM back to LPH?
A: Yes, to convert back, use the formula: LPH = GPM × 227.12470704
