1. What is a Flow Rate Unit Conversion Calculator?

Definition: This calculator converts flow rate measurements between liters per minute (LPM), cubic meters per hour (m³/h), and gallons per minute (GPM).

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

2. How Does the Calculator Work?

The calculator uses these conversion formulas:

\[ Q_{gpm} = \frac{Q_{lpm}}{3.785} \] \[ Q_{gpm} = Q_{m3h} \times 4.402 \]

Where:

Explanation: The calculator converts either LPM or m³/h input to GPM using standard conversion factors.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is essential for system design, equipment specification, and process control in various industries including water treatment, chemical processing, and HVAC.

4. Using the Calculator

Tips: Enter either LPM or m³/h value (not both) and click "Convert to GPM". The calculator will provide the equivalent flow rate in gallons per minute.

5. Frequently Asked Questions (FAQ)

Q1: Why convert to GPM?
A: Gallons per minute is a standard unit in many industries, especially in the United States, making it useful for comparing specifications.

Q2: What's the conversion factor between LPM and GPM?
A: 1 GPM equals approximately 3.785 LPM (since 1 gallon = 3.785 liters).

Q3: How do I convert m³/h to GPM?
A: Multiply m³/h by 4.402 to get GPM (1 m³/h ≈ 4.402 GPM).

Q4: Can I convert GPM back to other units?
A: Yes, use the inverse operations: LPM = GPM × 3.785 and m³/h = GPM ÷ 4.402.

Q5: Are these conversions exact?
A: They're based on standard conversion factors, but for precise engineering work, always verify the specific conversion factors for your application.
