Flow Rate Conversion:
| From: | To: |
The 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 units.
Details: Accurate flow rate conversion is crucial in water treatment plants, chemical processing, irrigation systems, and HVAC applications where precise flow measurements are necessary for system design and operation.
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).
Q1: What is the exact conversion factor?
A: The exact conversion factor is 0.22712470704 m³/hr per GPM, based on 1 gallon = 0.00378541 cubic meters and 1 hour = 60 minutes.
Q2: When is this conversion typically used?
A: This conversion is commonly used in international engineering projects, fluid dynamics calculations, and when working with equipment specifications from different countries.
Q3: How accurate is this conversion?
A: The conversion is mathematically exact based on standard unit definitions. However, ensure you're using the same gallon definition (US gallon) for consistency.
Q4: Can I convert back from m³/hr to GPM?
A: Yes, to convert back, divide the m³/hr value by 0.22712470704 or multiply by approximately 4.40287.
Q5: Are there different types of gallons?
A: Yes, this calculator uses US gallons. Imperial gallons are about 20% larger, so the conversion factor would be different for imperial gallons.
