1. What Is GPM To M³/Hr Conversion?

GPM to m³/hr conversion is used to convert flow rates from gallons per minute (imperial/US gallon) to cubic meters per hour. This conversion is essential in various engineering, plumbing, and industrial applications where different measurement 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: The conversion factor is derived from the relationship between gallons and cubic meters, and minutes to hours (1 gallon = 0.00378541 m³, 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 when working with equipment specifications that use different measurement systems.

4. Using The Converter

Tips: Enter the flow rate in gallons per minute (GPM). The converter will automatically calculate the equivalent value in cubic meters per hour (m³/hr). Values must be non-negative.

5. Frequently Asked Questions (FAQ)

Q1: What is the exact conversion factor from GPM to m³/hr?
A: The exact conversion factor is 0.22712470704, which comes from 0.00378541 (gallons to m³) × 60 (minutes to hours).

Q2: Does this conversion use US gallons or imperial gallons?
A: This conversion uses US gallons (1 US gallon = 3.78541 liters). Imperial gallons are larger (1 imperial gallon = 4.54609 liters).

Q3: When is this conversion typically used?
A: Commonly used in water treatment plants, HVAC systems, industrial processes, and when converting between metric and imperial flow rate specifications.

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

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