1. What is Flow Rate Conversion?

Flow rate conversion between cubic meters per hour (m³/hr) and US gallons per minute (US GPM) is essential in various engineering, industrial, and scientific applications where fluid flow measurements need to be translated between metric and US customary units.

2. How Does the Converter Work?

The converter uses the precise conversion formula:

Where:

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

Explanation: This conversion factor is derived from the relationship between cubic meters and US gallons, and hours to minutes.

3. Importance of Flow Rate Conversion

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

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 US gallons per minute.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between US gallons and imperial gallons?
A: US gallons (3.785 liters) are smaller than imperial gallons (4.546 liters). This converter uses US gallons, which are standard in the United States.

Q2: How accurate is the conversion factor?
A: The factor 4.402867539302473 is precise and accounts for the exact relationship between cubic meters and US gallons.

Q3: Where is this conversion commonly used?
A: Commonly used in water treatment, HVAC systems, chemical processing, oil and gas industry, and any application involving fluid flow measurements.

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

Q5: What are typical flow rate ranges?
A: Residential water systems: 5-20 US GPM (0.68-2.73 m³/hr), industrial processes: 100-1000+ US GPM (13.6-136+ m³/hr).
