1. What is GPM to m³/hr Conversion?

The GPM to m³/hr conversion is used to convert flow rate measurements from gallons per minute (GPM) to cubic meters per hour (m³/hr). This conversion is essential in various engineering, industrial, and scientific applications where fluid flow rates need to be expressed in different unit systems.

2. How Does the Conversion Work?

The conversion uses the following formula:

Where:

• \( GPM \) — Flow rate in gallons per minute
• \( 0.22712470704 \) — Conversion factor (exact value)

Explanation: The conversion factor accounts for the relationship between gallons and cubic meters (1 gallon = 0.00378541 cubic meters) and the time conversion from minutes to hours (60 minutes = 1 hour).

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for international engineering projects, fluid system design, pump specifications, and compliance with different measurement standards used worldwide.

4. Using the Calculator

Tips: Enter the flow rate in gallons per minute (GPM). The calculator will automatically convert it to cubic meters per hour (m³/hr). The default value is set to 200 GPM for quick conversion.

5. Frequently Asked Questions (FAQ)

Q1: Why convert GPM to m³/hr?
A: Different countries and industries use different measurement systems. Converting between units ensures clear communication and accurate specifications in international projects.

Q2: What is the exact conversion factor?
A: The exact conversion factor is 0.22712470704, derived from 1 gallon = 0.00378541 m³ and 60 minutes = 1 hour.

Q3: Where is this conversion commonly used?
A: Commonly used in water treatment plants, HVAC systems, petroleum industry, chemical processing, and hydraulic engineering.

Q4: How accurate is this conversion?
A: The conversion is mathematically exact. Accuracy depends on the precision of the input GPM value.

Q5: Can I convert back from m³/hr to GPM?
A: Yes, use the inverse conversion: GPM = m³/hr ÷ 0.22712470704 or GPM = m³/hr × 4.40287.
