Flow Rate Conversion Formula:
| From: | To: |
The GPM to CFM conversion calculates the equivalent flow rate from gallons per minute to cubic feet per minute. This conversion is essential in fluid dynamics, HVAC systems, and engineering applications where different flow rate units are used.
The calculator uses the conversion formula:
Where:
Explanation: The conversion factor is derived from the relationship between volume units where 1 US gallon equals 0.13368055555554628 cubic feet.
Details: Accurate flow rate conversion is crucial for system design, pump selection, pipe sizing, and ensuring compatibility between different measurement systems in engineering and industrial applications.
Tips: Enter the flow rate in gallons per minute (GPM). The value must be positive. The calculator will automatically convert it to cubic feet per minute (CFM).
Q1: What is the difference between GPM and CFM?
A: GPM measures liquid flow rate in gallons per minute, while CFM measures gas or air flow rate in cubic feet per minute. The conversion allows comparison between different fluid types.
Q2: Is the conversion factor exact?
A: Yes, the conversion factor 0.13368055555554628 is exact based on the US gallon to cubic foot relationship (1 gallon = 0.13368055555554628 ft³).
Q3: When is this conversion most commonly used?
A: Commonly used in HVAC systems, hydraulic engineering, pump specifications, and when converting between liquid and gas flow measurements in industrial applications.
Q4: Can this conversion be used for any fluid?
A: Yes, the conversion is based on volume units and is valid for any fluid, though density differences may affect mass flow rates.
Q5: What are typical GPM values in practical applications?
A: Residential water systems: 2-10 GPM, industrial pumps: 50-1000+ GPM, HVAC systems vary widely based on application requirements.
