1. What is a GPH to LPM Calculator?

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 Calculator Work?

The calculator uses the formula:

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

Where:

\( Q_{lpm} \) — Flow rate in liters per minute (LPM)
\( Q_{gph} \) — Flow rate in gallons per hour (GPH)

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

3. Importance of Flow Rate Conversion

Details: Accurate conversion between units is essential for system design, pump selection, and process control in fluid systems.

4. Using the Calculator

Tips: Simply enter the flow rate in gallons per hour (GPH) and the calculator will provide the equivalent in liters per minute (LPM).

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 and system design.

Q2: What's the conversion factor from GPH to LPM?
A: 1 GPH = 0.0631 LPM (exactly 3.785/60).

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

Q4: How accurate is this conversion?
A: The conversion is mathematically exact based on the definition of gallons and liters.

Q5: Can I convert LPM back to GPH?
A: Yes, use the inverse formula: \( Q_{gph} = Q_{lpm} \times 60 / 3.785 \).
