1. What is GPM to CFM Conversion?

GPM to CFM conversion is the process of converting flow rate measurements from gallons per minute to cubic feet per minute. This conversion is essential in various engineering and fluid dynamics applications where different units of flow measurement are used.

2. How Does the Conversion Work?

The conversion uses the following formula:

\[ CFM = GPM \times 0.13368055555554628 \]

Where:

\( GPM \) — Gallons per minute
\( CFM \) — Cubic feet per minute
\( 0.13368055555554628 \) — Conversion factor (1 gallon = 0.13368055555554628 cubic feet)

Explanation: The conversion factor is derived from the relationship between gallons and cubic feet, where 1 US gallon equals approximately 0.13368 cubic feet.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial in HVAC systems, hydraulic engineering, plumbing design, and industrial processes where consistent unit measurement is necessary for proper system design and operation.

4. Using the Converter

Tips: Enter the flow rate in gallons per minute (GPM). The value must be non-negative. The converter will automatically calculate the equivalent value in cubic feet per minute (CFM).

5. Frequently Asked Questions (FAQ)
