1. What is Water Flow Rate Conversion?

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

Purpose: It helps engineers, plumbers, and technicians work with different flow rate units used in various systems and regions.

2. How Does the Calculator Work?

The calculator uses these formulas:

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

Where:

\( Q_{gpm} \) — Flow rate in gallons per minute
\( Q_{lpm} \) — Flow rate in liters per minute
\( Q_{m3h} \) — Flow rate in cubic meters per hour

Explanation: The conversions are based on standard unit relationships where 1 gallon = 3.785 liters and 1 m³/h = 4.402 GPM.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion ensures proper system design, performance evaluation, and compatibility between components using different measurement standards.

4. Using the Calculator

Tips: Enter either LPM or m³/h value (not both) and click convert. The calculator will provide the equivalent flow rate in GPM.

5. Frequently Asked Questions (FAQ)

Q1: Why convert to GPM?
A: GPM is commonly used in US systems, while LPM and m³/h are metric standards. Conversion allows comparison and system integration.

Q2: What's the accuracy of these conversions?
A: The conversions are mathematically exact based on standard unit definitions.

Q3: Can I convert both LPM and m³/h at once?
A: No, enter only one value at a time as they represent different flow rates.

Q4: Does this work for other liquids besides water?
A: Yes, for liquids with similar density to water. For viscous fluids, additional factors may be needed.

Q5: How do I convert back from GPM?
A: Use the inverse formulas: LPM = GPM × 3.785 and m³/h = GPM / 4.402.
