1. What is GPM to CFM Conversion?

The GPM to CFM conversion is used to convert flow rate measurements from gallons per minute (GPM) to cubic feet per minute (CFM). This conversion is essential in various engineering and fluid dynamics applications.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

\[ CFM = GPM \times 0.13368055555554628 \]

Where:

\( GPM \) — Flow rate in gallons per minute
\( CFM \) — Flow rate in cubic feet per minute
\( 0.13368055555554628 \) — Conversion factor (1 gallon = 0.13368055555554628 cubic feet)

Explanation: Since 1 US gallon equals 0.13368055555554628 cubic feet, multiplying GPM by this factor gives the equivalent flow rate in CFM.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for HVAC systems, hydraulic engineering, pump sizing, ventilation design, and various industrial applications where fluid flow measurements need to be standardized across different units.

4. Using the Calculator

Tips: Enter the flow rate in gallons per minute (GPM). The value must be positive. The calculator will instantly convert it to cubic feet per minute (CFM).

5. Frequently Asked Questions (FAQ)

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 definition (1 gallon = 231 cubic inches, 1 cubic foot = 1728 cubic inches).

Q3: When is this conversion most commonly used?
A: Commonly used in HVAC systems, water treatment plants, hydraulic systems, and when comparing liquid and gas flow rates in engineering applications.

Q4: Can this conversion be used for any fluid?
A: The conversion is volumetric and works for any fluid, but density differences between fluids will affect mass flow rates and pressure requirements.

Q5: How accurate is this conversion?
A: The conversion is mathematically exact. Accuracy depends on the precision of your initial GPM measurement.
