1. What is CFM to GPM Conversion?

CFM (Cubic Feet per Minute) to GPM (Gallons per Minute) conversion is used to convert volumetric flow rates between different units of measurement. This conversion is essential in fluid dynamics, HVAC systems, plumbing, and various engineering applications.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( GPM \) — Gallons per minute
• \( CFM \) — Cubic feet per minute
• \( 7.48051948051948 \) — Conversion factor (gallons per cubic foot)

Explanation: One cubic foot contains approximately 7.48 gallons, so multiplying CFM by this factor converts the flow rate to gallons per minute.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for system design, pump selection, pipe sizing, and ensuring proper fluid handling in various industrial and residential applications.

4. Using the Calculator

Tips: Enter the CFM value in cubic feet per minute. The value must be positive. The calculator will automatically compute the equivalent flow rate in gallons per minute.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 7.48051948051948?
A: This factor represents the number of US liquid gallons in one cubic foot (1 ft³ = 7.48051948 gallons).

Q2: Does this conversion work for all fluids?
A: Yes, this is a volumetric conversion that works for any fluid, as it converts volume per time regardless of the fluid's density.

Q3: When is CFM to GPM conversion typically used?
A: Commonly used in water systems, HVAC calculations, irrigation design, and any application involving liquid flow measurements.

Q4: Are there different gallon measurements to consider?
A: This calculator uses US liquid gallons. For imperial gallons, the conversion factor would be different (1 ft³ = 6.22883 imperial gallons).

Q5: How accurate is this conversion?
A: The conversion is mathematically exact based on the defined relationship between cubic feet and gallons.
