1. What is Flow Rate Conversion?

Flow rate conversion between gallons per minute (GPM) and cubic meters per hour (m³/hr) is essential in various engineering, industrial, and scientific applications where fluid flow measurements need to be standardized across different unit systems.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( GPM \) — Flow rate in gallons per minute
• \( 0.22712470704 \) — Conversion factor from GPM to m³/hr

Explanation: This conversion factor is derived from the relationship between US gallons and cubic meters, where 1 US gallon = 0.00378541 cubic meters and 1 hour = 60 minutes.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for international engineering projects, fluid system design, pump sizing, and ensuring compatibility between equipment using different measurement systems.

4. Using the Calculator

Tips: Enter the flow rate in gallons per minute (GPM). The value must be non-negative. The calculator will automatically convert it to cubic meters per hour (m³/hr).

5. Frequently Asked Questions (FAQ)

Q1: What is the exact conversion factor?
A: The precise conversion factor is 0.22712470704 m³/hr per GPM.

Q2: Are there different types of gallons?
A: Yes, this calculator uses US gallons. Imperial gallons have a different conversion factor (1 imperial gallon = 0.00454609 m³).

Q3: When is this conversion commonly used?
A: Commonly used in water treatment plants, HVAC systems, petroleum industry, and any application involving fluid flow measurements.

Q4: How accurate is this conversion?
A: The conversion is mathematically exact based on standard unit definitions.

Q5: Can I convert back from m³/hr to GPM?
A: Yes, to convert back, divide m³/hr by 0.22712470704 or multiply by approximately 4.40287.
