1. What is GPM to m³/hr Conversion?

The GPM to m³/hr conversion calculates water flow rate from gallons per minute to cubic meters per hour. This conversion is essential for engineering, plumbing, and water management applications where different measurement systems are used.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( GPM \) — Gallons per minute (US gallons)
• \( 0.22712470704 \) — Conversion factor

Explanation: One US gallon per minute equals approximately 0.227 cubic meters per hour. The conversion factor is derived from the relationship between gallons and cubic meters (1 gallon = 0.00378541 cubic meters) and minutes to hours (60 minutes = 1 hour).

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for international projects, engineering calculations, pump sizing, pipe design, and water system planning where metric and imperial units need to be reconciled.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

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

Q2: Are US gallons and imperial gallons the same?
A: No, US gallons (3.78541 liters) are different from imperial gallons (4.54609 liters). This calculator uses US gallons.

Q3: When is this conversion typically used?
A: Commonly used in water treatment plants, irrigation systems, industrial processes, and international engineering projects.

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

Q5: Can this be used for fluids other than water?
A: Yes, the volume conversion applies to any fluid, but density differences may affect mass flow rate calculations.
