1. What is m³/h to GPH Conversion?

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

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q_{gph} \) — Flow rate in gallons per hour (GPH)
• \( Q_{m3h} \) — Flow rate in cubic meters per hour (m³/h)
• 4.402 — Gallons in one cubic meter
• 60 — Conversion factor from minutes to hours

Explanation: The formula converts the volume unit (cubic meters to gallons) while maintaining the time unit (per hour).

3. Importance of Flow Rate Conversion

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

4. Using the Calculator

Tips: Simply enter the flow rate in cubic meters per hour (m³/h) and the calculator will automatically compute the equivalent in gallons per hour (GPH).

5. Frequently Asked Questions (FAQ)

Q1: Why multiply by both 4.402 and 60?
A: 4.402 converts cubic meters to gallons, and 60 converts minutes to hours (since 1 m³ = 1000 liters and 1 gallon = 3.785 liters).

Q2: What's the typical application for this conversion?
A: Commonly used when working with international equipment specifications or when comparing systems using different measurement standards.

Q3: How accurate is this conversion?
A: The conversion is mathematically precise, though actual flow rates may vary slightly due to temperature and pressure conditions.

Q4: Can I convert GPH back to m³/h?
A: Yes, use the inverse formula: \( Q_{m3h} = Q_{gph} \div (4.402 \times 60) \).

Q5: Does this work for all liquids?
A: Yes, this is a volumetric conversion that works for any liquid, though mass flow rates would require density considerations.
