1. What is GPM to CFM Conversion?

GPM (Gallons Per Minute) to CFM (Cubic Feet Per Minute) conversion is used to convert flow rates between liquid volume measurement (gallons) and gas volume measurement (cubic feet). 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: 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 for HVAC systems, hydraulic engineering, pump sizing, ventilation design, and various industrial applications where both liquid and gas flow rates need to be compared or converted.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 0.13368055555554628?
A: This factor comes from the exact conversion where 1 US gallon = 231 cubic inches and 1 cubic foot = 1728 cubic inches, resulting in 231/1728 = 0.13368055555554628.

Q2: Is this conversion applicable for all fluids?
A: Yes, the conversion is based on volume and is applicable for any fluid, though density differences may affect mass flow rates.

Q3: When would I need to convert GPM to CFM?
A: Common applications include HVAC system design, hydraulic calculations, pump specifications, and when comparing liquid and gas flow rates in mixed systems.

Q4: Are there different conversion factors for imperial gallons?
A: Yes, imperial gallons are larger (1 imperial gallon = 0.160544 cubic feet), so a different conversion factor would be needed for imperial measurements.

Q5: How accurate is this conversion?
A: The conversion is mathematically exact based on standard volume definitions, making it highly accurate for engineering purposes.
