1. What is Fuel Pump Flow Rate?

Fuel pump flow rate measures how much fuel a pump can deliver in a given time, typically expressed in gallons per hour (GPH) or liters per hour (LPH). It's a critical specification for engine performance and fuel system design.

2. How Does the Conversion Work?

The conversion between GPH and LPH uses this simple formula:

Where:

• 1 US gallon = 3.785 liters
• GPH — Gallons per hour
• LPH — Liters per hour

Explanation: Since 1 US gallon equals exactly 3.785 liters, multiplying GPH by this conversion factor gives the equivalent flow rate in liters per hour.

3. Importance of Flow Rate Conversion

Details: Converting between GPH and LPH is essential when working with international specifications, comparing pumps from different manufacturers, or designing fuel systems that use metric measurements.

4. Using the Calculator

Tips: Enter the flow rate in GPH (gallons per hour) and the calculator will automatically compute the equivalent in LPH (liters per hour). The value must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: Why convert between GPH and LPH?
A: Different regions and manufacturers use different units, so conversion is needed for accurate comparisons and system design.

Q2: Is this conversion exact?
A: Yes, 1 US gallon is exactly 3.785 liters by definition, making the conversion mathematically precise.

Q3: What's a typical fuel pump flow rate?
A: Automotive fuel pumps typically range from 30-300 GPH (114-1136 LPH), depending on engine requirements.

Q4: Does temperature affect the conversion?
A: The conversion factor is constant, but actual fuel volume varies slightly with temperature due to thermal expansion.

Q5: Can I convert LPH back to GPH?
A: Yes, divide LPH by 3.785 to get GPH (GPH = LPH ÷ 3.785).
