1. What is CFS to GPM Conversion?

The CFS to GPM conversion is used to convert flow rate from cubic feet per second (CFS) to gallons per minute (GPM). This conversion is commonly used in hydraulic engineering, water management, and fluid dynamics applications.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( CFS \) — Flow rate in cubic feet per second
• \( 448.831 \) — Conversion factor from CFS to GPM

Explanation: The conversion factor 448.831 is derived from the relationship between cubic feet and gallons, and seconds to minutes conversion.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for water system design, irrigation planning, pump sizing, and various engineering applications where different measurement units are used.

4. Using the Calculator

Tips: Enter the flow rate in cubic feet per second (CFS). The value must be a positive number. 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 448.831?
A: This factor comes from 1 cubic foot = 7.48052 gallons and 1 minute = 60 seconds (7.48052 × 60 = 448.8312).

Q2: When would I need to convert CFS to GPM?
A: This conversion is useful when working with water flow measurements in different unit systems, particularly in US customary units for various engineering applications.

Q3: What are typical CFS values in real-world applications?
A: Small streams might flow at 1-10 CFS, while larger rivers can flow at hundreds or thousands of CFS. Municipal water systems often use GPM for smaller flows.

Q4: Is this conversion accurate for all fluids?
A: The conversion factor is based on water density. For other fluids with different densities, additional conversion factors may be needed.

Q5: Can I convert GPM back to CFS?
A: Yes, you can use the inverse formula: \( CFS = GPM \div 448.831 \)
