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 different unit systems are used.
The conversion uses the following formula:
Where:
Explanation: This conversion factor is derived from the relationship between gallons and cubic meters, and minutes to hours. One US gallon equals approximately 0.00378541 cubic meters, and there are 60 minutes in an hour.
Details: Accurate flow rate conversion is crucial in water treatment plants, chemical processing, HVAC systems, and international engineering projects where different measurement systems are used. Proper conversion ensures consistency and accuracy in calculations and system design.
Tips: Enter the flow rate in gallons per minute (GPM). The value must be non-negative. The converter will automatically calculate the equivalent flow rate in cubic meters per hour (m³/hr).
Q1: What is the difference between US gallon and imperial gallon?
A: The conversion uses US gallons (3.78541 liters). Imperial gallons are larger (4.54609 liters) and would require a different conversion factor.
Q2: How accurate is this conversion?
A: The conversion factor 0.22712470704 is exact for US gallons. The calculator provides results with 6 decimal places for precision.
Q3: When is this conversion typically used?
A: Commonly used in water supply systems, irrigation, industrial fluid handling, and international engineering specifications.
Q4: Can I convert m³/hr back to GPM?
A: Yes, use the inverse conversion: GPM = m³/hr ÷ 0.22712470704 or GPM = m³/hr × 4.40287.
Q5: Are there any limitations to this conversion?
A: This conversion is specific to US gallons. For imperial gallons or other volume units, different conversion factors apply.
