1. What is Flow Rate Conversion?

Flow rate conversion between cubic meters per hour (m³/h) 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 uses the following formula:

Where:

• \( m³/h \) — Flow rate in cubic meters per hour
• \( 4.402867539302473 \) — Conversion factor

Explanation: This conversion factor accounts for the volume difference between cubic meters and gallons, and the time conversion from hours to 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 so precise?
A: The factor 4.402867539302473 accounts for exact conversions: 1 cubic meter = 264.172 gallons and 1 hour = 60 minutes.

Q2: When would I need to convert between m³/h and GPM?
A: Common in plumbing, HVAC systems, industrial processes, water treatment plants, and when working with international equipment specifications.

Q3: Are there different types of gallons?
A: This conversion uses US gallons. Imperial gallons (UK) use a different conversion factor of approximately 4.54609 liters vs. 3.78541 liters for US gallons.

Q4: What is a typical flow rate range?
A: Residential water systems: 5-20 GPM (1.1-4.5 m³/h), industrial pumps: 100-1000+ GPM (22.7-227+ m³/h).

Q5: Can I convert GPM back to m³/h?
A: Yes, use the inverse: \( m³/h = GPM \div 4.402867539302473 \) or \( m³/h = GPM \times 0.227124 \).
