1. What is a GPM to L/hr Calculator?

Definition: This calculator converts flow rate from gallons per minute (GPM) to liters per hour (L/hr).

Purpose: It helps engineers, technicians, and professionals working with fluid systems to easily convert between these common flow rate units.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Q_{lph} = Q_{gpm} \times 3.785 \times 60 \]

Where:

\( Q_{lph} \) — Flow rate in liters per hour
\( Q_{gpm} \) — Flow rate in gallons per minute
3.785 — Conversion factor (liters per gallon)
60 — Conversion factor (minutes per hour)

Explanation: The conversion accounts for both volume units (gallons to liters) and time units (minutes to hours).

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is essential for system design, pump sizing, and comparing specifications that may use different units.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why convert GPM to L/hr?
A: Many international standards and equipment specifications use metric units (L/hr), while some systems still use GPM.

Q2: How accurate is this conversion?
A: The conversion is mathematically exact based on standard conversion factors.

Q3: What's the conversion factor breakdown?
A: 1 gallon = 3.785 liters, and 1 hour = 60 minutes, hence the multiplier of 227.1 (3.785 × 60).

Q4: Can I convert L/hr back to GPM?
A: Yes, divide L/hr by 227.1 to get GPM.

Q5: Does this work for any liquid?
A: Yes, the conversion is based on volume flow rate, not the liquid's properties.
