Flow Rate Conversion Formula:
| From: | To: |
GPM to m³/hr conversion is used to convert flow rate measurements from gallons per minute to cubic meters per hour. This conversion is essential in various engineering, industrial, and scientific applications where different unit systems are used.
The calculator uses the conversion formula:
Where:
Explanation: One gallon per minute equals approximately 0.227 cubic meters per hour based on the standard conversion factors between imperial and metric volume units.
Details: Accurate flow rate conversion is crucial for international engineering projects, fluid dynamics calculations, pump sizing, pipeline design, and compliance with different measurement standards used worldwide.
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 of 250 GPM is pre-filled for quick conversion.
Q1: What is the exact conversion factor from GPM to m³/hr?
A: The exact conversion factor is 0.22712470704, which is derived from the relationship between gallons and cubic meters (1 gallon = 0.00378541 m³) and the time conversion (60 minutes = 1 hour).
Q2: How accurate is this conversion?
A: This conversion is mathematically exact based on standard unit definitions. The calculator provides results with 4 decimal places for precision.
Q3: When is this conversion commonly used?
A: This conversion is frequently used in water treatment plants, hydraulic engineering, irrigation systems, chemical processing, and any application involving fluid flow measurements.
Q4: Are there different types of gallons that affect the conversion?
A: This calculator uses the US liquid gallon (3.78541 liters). The Imperial gallon (4.54609 liters) would require a different conversion factor of approximately 0.272765.
Q5: Can I convert back from m³/hr to GPM?
A: Yes, to convert from m³/hr to GPM, divide by 0.22712470704 or multiply by approximately 4.40287.
