Conversion Formula:
| From: | To: |
The CFPM to GPM conversion is used to convert flow rates from cubic feet per minute to gallons per minute. This conversion is essential in various engineering, plumbing, and fluid dynamics applications where different measurement units are used.
The calculator uses the conversion formula:
Where:
Explanation: One cubic foot contains approximately 7.48 gallons, so the conversion multiplies the cubic feet per minute value by this factor to get gallons per minute.
Details: Accurate flow rate conversion is crucial for system design, pump selection, pipe sizing, and ensuring proper fluid handling in various industrial and domestic applications.
Tips: Enter the flow rate in cubic feet per minute (CFPM). The value must be non-negative. The calculator will automatically compute the equivalent flow rate in gallons per minute (GPM).
Q1: Why is the conversion factor 7.48051948051948?
A: This factor comes from the definition of a gallon (231 cubic inches) and a cubic foot (1728 cubic inches). 1728 ÷ 231 = 7.48051948051948 gallons per cubic foot.
Q2: What are typical CFPM values in practical applications?
A: CFPM values vary widely depending on the application - from small residential systems (0.1-5 CFPM) to large industrial processes (100+ CFPM).
Q3: Is this conversion applicable to all fluids?
A: Yes, this conversion is valid for all fluids since it's a volumetric conversion. However, for mass flow rates, density considerations would be needed.
Q4: How accurate is this conversion?
A: The conversion is mathematically exact based on standard definitions. Accuracy depends on the precision of your input measurement.
Q5: Are there different gallon definitions that affect this conversion?
A: This calculator uses the US liquid gallon (231 cubic inches). The imperial gallon (UK) is different (277.42 cubic inches) and would require a different conversion factor.
