1. What is GPM to ft³/min Conversion?

The GPM to ft³/min conversion is used to convert flow rate measurements from gallons per minute to cubic feet per minute. This conversion is essential in various engineering, plumbing, and fluid dynamics applications where different unit systems are used.

2. How Does the Conversion Work?

The conversion uses the following formula:

Where:

• \( GPM \) — Flow rate in gallons 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 converts the flow rate to cubic feet per minute.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for engineering calculations, pipe sizing, pump selection, and system design where consistent units are required across different measurement systems.

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 flow rate in cubic feet per minute.

5. Frequently Asked Questions (FAQ)

Q1: What is the exact conversion factor?
A: The exact conversion factor is 0.13368055555554628, which comes from the fact that 1 US gallon = 231 cubic inches and 1 cubic foot = 1728 cubic inches.

Q2: Is this conversion for US gallons or imperial gallons?
A: This conversion uses US gallons. Imperial gallons are larger (1 imperial gallon = 0.16054365 cubic feet).

Q3: Where is this conversion commonly used?
A: Commonly used in HVAC systems, plumbing design, hydraulic engineering, and industrial processes in the United States.

Q4: How accurate is this conversion?
A: The conversion is mathematically exact based on standard definitions of US gallons and cubic feet.

Q5: Can I convert back from ft³/min to GPM?
A: Yes, to convert back, divide ft³/min by 0.13368055555554628 or multiply by approximately 7.48052.
