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 different unit systems are used.

2. How Does the Conversion Work?

The conversion formula is:

Where:

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

Explanation: The conversion factor is derived from the relationship between gallons and cubic meters, and minutes and hours. One US gallon equals approximately 0.00378541 cubic meters, and one hour contains 60 minutes.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial in water treatment plants, chemical processing, HVAC systems, and international engineering projects where metric units are standard.

4. Using the Converter

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