1. What is CFS to GPM Conversion?

The CFS to GPM conversion is used to convert flow rate measurements from cubic feet per second to gallons per minute. This conversion is essential in various engineering, hydraulic, and fluid dynamics applications where different units of flow measurement are used.

2. How Does the Conversion Work?

The conversion uses the formula:

Where:

• \( GPM \) — Gallons per minute
• \( CFS \) — Cubic feet per second
• \( 448.8311688312 \) — Conversion factor

Explanation: The conversion factor is derived from the relationship between cubic feet and gallons (1 cubic foot = 7.48052 gallons) and the conversion from seconds to minutes (1 minute = 60 seconds).

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for hydraulic engineering, water resource management, pump sizing, pipeline design, and irrigation system planning where different measurement units are commonly used.

4. Using the Converter

Tips: Enter the flow rate in cubic feet per second (CFS). The value must be non-negative. The converter will automatically calculate the equivalent flow rate in gallons per minute (GPM).

5. Frequently Asked Questions (FAQ)

Q1: What is the exact conversion factor?
A: The precise conversion factor is 448.8311688312, which comes from 7.48052 (gallons per cubic foot) × 60 (seconds per minute).

Q2: When is CFS commonly used?
A: CFS is commonly used in river flow measurements, large-scale water distribution systems, and hydraulic engineering projects.

Q3: When is GPM typically used?
A: GPM is frequently used in plumbing, pump specifications, irrigation systems, and smaller-scale fluid applications.

Q4: Can I convert GPM back to CFS?
A: Yes, to convert GPM to CFS, divide the GPM value by 448.8311688312.

Q5: What's the difference between US gallon and imperial gallon?
A: This converter uses US gallons (1 US gallon = 231 cubic inches). Imperial gallons are larger (1 imperial gallon = 277.42 cubic inches).
