Flow Rate Conversion Formula:
| From: | To: |
The GPM to m³/hr conversion is used to convert flow rate measurements from gallons per minute (GPM) to cubic meters per hour (m³/hr). This conversion is essential in various engineering, industrial, and scientific applications where fluid flow rates need to be expressed in different unit systems.
The calculator uses the conversion formula:
Where:
Explanation: This conversion factor is derived from the relationship between US gallons and cubic meters, and the conversion from minutes to hours.
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 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 the US gallon definition (1 gallon = 0.00378541 cubic meters).
Q2: Does this conversion work for imperial gallons?
A: No, this conversion is specifically for US gallons. Imperial gallons use a different conversion factor (approximately 0.272765 m³/hr per imperial GPM).
Q3: Where is this conversion commonly used?
A: This conversion is widely used in water treatment plants, chemical processing, HVAC systems, irrigation design, and international engineering projects.
Q4: How accurate is this conversion?
A: The conversion is mathematically exact based on standard unit definitions. However, practical accuracy depends on the precision of your input measurement.
Q5: 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.
