1. What is CFS to GPM Conversion?

The CFS (cubic feet per second) to GPM (gallons per minute) conversion is used to convert flow rate measurements between these two common units. This conversion is essential in hydraulic engineering, water resource management, and fluid dynamics applications.

2. How Does the Calculator Work?

The calculator uses the conversion 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 = 7.48051948 gallons) and the conversion between seconds and minutes (1 minute = 60 seconds).

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for engineering calculations, water system design, irrigation planning, and environmental monitoring where different measurement units are used in various contexts.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 448.8311688312?
A: This factor comes from multiplying 7.48051948 (gallons per cubic foot) by 60 (seconds per minute): 7.48051948 × 60 = 448.8311688.

Q2: When would I need to convert CFS to GPM?
A: Common applications include water supply system design, hydraulic calculations, pump specifications, and when working with equipment that uses different flow rate units.

Q3: What are typical CFS values in real-world applications?
A: Small streams might flow at 1-10 CFS, rivers at 100-1,000 CFS, while large water supply systems may handle thousands of CFS.

Q4: Is this conversion exact?
A: The conversion factor is mathematically exact based on the defined relationships between the units.

Q5: Can I convert GPM back to CFS?
A: Yes, use the inverse formula: CFS = GPM ÷ 448.8311688312.
