1. What is a GPH to LPM Converter?

Definition: This calculator converts flow rate from gallons per hour (GPH) to liters per minute (LPM).

Purpose: It helps engineers, technicians, and fluid system designers convert between these common flow rate units.

2. How Does the Converter Work?

The converter uses the 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

Explanation: First converts hours to minutes (÷60), then gallons to liters (×3.785).

3. Importance of Flow Rate Conversion

Details: Accurate conversion ensures proper system design, pump sizing, and process control in fluid systems.

4. Using the Converter

Tips: Simply enter the flow rate in GPH. The calculator will automatically compute the equivalent LPM value.

5. Frequently Asked Questions (FAQ)

Q1: Why convert between GPH and LPM?
A: Different industries and regions use different units, and conversion is often needed for equipment specifications.

Q2: What's the conversion factor from GPH to LPM?
A: 1 GPH equals approximately 0.0631 LPM (or 1 LPM ≈ 15.85 GPH).

Q3: When would I need this conversion?
A: When working with international equipment, comparing pump specs, or designing fluid systems with mixed-unit components.

Q4: Is this conversion valid for all liquids?
A: Yes, for volume flow rate. For mass flow rate, you'd need to consider fluid density.

Q5: How precise is this conversion?
A: The conversion uses the exact definition (1 US gallon = 3.785411784 liters), so it's highly precise.
