1. What Is Flow Rate Conversion?

Flow rate conversion between cubic meters per hour (m³/hr) and gallons per minute (GPM) is essential for engineers, technicians, and professionals working with fluid systems across different measurement standards.

2. How Does The Conversion Work?

The conversion formula is:

Where:

• \( m³/hr \) — Flow rate in cubic meters per hour
• \( GPM \) — Flow rate in gallons per minute
• \( 4.402867539302473 \) — Conversion factor

Explanation: This conversion factor is derived from the relationship between cubic meters and gallons (1 m³ = 264.172 gallons) and the time conversion between hours and minutes (1 hour = 60 minutes).

3. Importance Of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for international projects, equipment specification, system design, and ensuring compatibility between components using different measurement systems.

4. Using The Converter

Tips: Enter the flow rate in cubic meters per hour. The value must be non-negative. The converter will automatically calculate the equivalent flow rate in gallons per minute.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 4.402867539302473?
A: This factor comes from: 1 m³/hr = (264.172 gallons) / (60 minutes) = 4.402867539302473 GPM.

Q2: What are typical applications for this conversion?
A: Water treatment plants, HVAC systems, industrial processes, pump sizing, pipeline design, and international engineering projects.

Q3: How accurate is this conversion?
A: The conversion is mathematically exact. Accuracy depends on the precision of your input measurement.

Q4: Can I convert GPM back to m³/hr?
A: Yes, use the inverse: m³/hr = GPM ÷ 4.402867539302473 or m³/hr = GPM × 0.227124.

Q5: Are there different types of gallons?
A: This converter uses US gallons (3.78541 liters). Imperial gallons are different (4.54609 liters).
