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: 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 international projects, engineering calculations, fluid dynamics, HVAC systems, water treatment plants, and industrial processes where different measurement systems are used.

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.
