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 uses the following formula:

Where:

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

Explanation: This conversion factor accounts for the relationship between US gallons and cubic meters, as well as the conversion from minutes to hours.

3. Importance of Flow Rate Conversion

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

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 25 GPM as specified.
