1. What is m3/hr to GPM Converter?

Definition: This calculator converts flow rate from cubic meters per hour (m³/h) to gallons per minute (GPM).

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

2. How Does the Converter Work?

The converter uses the formula:

\[ Q_{gpm} = Q_{m3h} \times 4.402 \]

Where:

\( Q_{gpm} \) — Flow rate in gallons per minute (GPM)
\( Q_{m3h} \) — Flow rate in cubic meters per hour (m³/h)
4.402 — Conversion factor (1 m³/h = 4.402 GPM)

Explanation: The conversion factor accounts for the volume difference between cubic meters and gallons, and the time difference between hours and minutes.

3. Importance of Flow Rate Conversion

Details: Accurate conversion between units is essential for system design, pump selection, and process control in various industries including water treatment, HVAC, and chemical processing.

4. Using the Converter

Tips: Simply enter the flow rate in cubic meters per hour (m³/h) and the converter will automatically calculate the equivalent in gallons per minute (GPM).

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 4.402?
A: It combines the conversion from cubic meters to gallons (1 m³ = 264.172 gallons) and hours to minutes (1 hour = 60 minutes).

Q2: When would I need this conversion?
A: When working with equipment specifications that use different units, or when comparing systems using different measurement standards.

Q3: How accurate is this conversion?
A: The conversion is mathematically exact, though actual flow measurements may have instrument precision limitations.

Q4: Can I convert GPM back to m³/h?
A: Yes, divide GPM by 4.402 to get m³/h, or use our GPM to m³/h converter tool.

Q5: Does this work for all liquids?
A: Yes, the conversion is based on volume flow rate, independent of the liquid type (though actual flow characteristics may vary by fluid properties).
