1. What is CFM to GPM Conversion?

The CFM to GPM conversion calculates water flow rate from cubic feet per minute to gallons per minute. This conversion is essential in fluid dynamics, plumbing, and engineering applications where different measurement units are used.

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: Since 1 cubic foot equals approximately 7.48052 gallons, multiplying CFM by this factor converts cubic feet per minute 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 water distribution in various engineering and industrial applications.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is the exact conversion factor?
A: The exact conversion factor is 7.48051948051948 gallons per cubic foot, based on the US liquid gallon definition.

Q2: Is this conversion specific to water?
A: Yes, this conversion is specifically for water. For other fluids, the conversion would depend on the fluid's density.

Q3: When is CFM to GPM conversion needed?
A: Commonly used in HVAC systems, plumbing design, irrigation systems, and industrial processes where flow rates need to be converted between different unit systems.

Q4: Are there different gallon definitions?
A: Yes, this calculator uses US liquid gallons. Imperial gallons (UK) use a different conversion factor (6.2288).

Q5: Can this be used for gas flow rates?
A: No, this conversion is specifically for liquid water. Gas flow rates require different considerations due to compressibility.
