1. What is an LPM to GPH Converter?

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

Purpose: It helps professionals and DIYers working with fluid systems to convert between these common flow rate units.

2. How Does the Converter Work?

The converter uses the formula:

Where:

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

Explanation: The formula first converts minutes to hours (×60) and liters to gallons (÷3.785).

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion ensures proper system design, equipment selection, and performance evaluation in fluid systems.

4. Using the Converter

Tips: Simply enter the flow rate in liters per minute (LPM). The value must be > 0.

5. Frequently Asked Questions (FAQ)

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

Q2: How precise is this conversion?
A: The conversion uses the standard value of 1 US gallon = 3.785 liters, which is precise for most practical applications.

Q3: Does this work for both liquid and gas flow?
A: Yes, but note that gas flow rates are often measured at standard conditions which may require additional corrections.

Q4: What's a typical flow rate in LPM for household water systems?
A: Typical household faucets flow at 5-10 LPM, while shower heads are often 6-9 LPM.

Q5: How would I convert back from GPH to LPM?
A: Use the inverse formula: \( Q_{lpm} = Q_{gph} \times \frac{3.785}{60} \)
