1. What is GPH to LPM Conversion?

GPH to LPM conversion is used to convert flow rates from gallons per hour to liters per minute. This conversion is essential in various engineering, industrial, and scientific applications where fluid flow measurements need to be converted between imperial and metric units.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

\[ Q_{lpm} = \frac{Q_{gph}}{60} \times 3.785 \]

Where:

\( Q_{lpm} \) — Flow rate in liters per minute
\( Q_{gph} \) — Flow rate in gallons per hour
60 — Conversion factor from hours to minutes
3.785 — Conversion factor from gallons to liters (1 gallon = 3.785 liters)

Explanation: The formula first converts gallons per hour to gallons per minute by dividing by 60, then converts gallons to liters by multiplying by 3.785.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial in hydraulic systems, fuel consumption calculations, chemical processing, and international engineering projects where different measurement systems are used.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why convert from GPH to LPM?
A: Conversion is necessary when working with international standards, comparing data from different sources, or using equipment that requires metric units.

Q2: What is the conversion factor from gallons to liters?
A: 1 US gallon = 3.785411784 liters. The calculator uses 3.785 for practical calculations.

Q3: Can this calculator be used for any fluid?
A: Yes, the conversion is volumetric and applies to any fluid. However, for mass flow rates, density considerations would be needed.

Q4: What are typical applications for this conversion?
A: Fuel flow in aviation/automotive, water treatment systems, chemical dosing, irrigation systems, and industrial process control.

Q5: How accurate is this conversion?
A: The conversion is mathematically exact. Accuracy depends on the precision of your input measurement and the specific gallon definition used.
