1. What is CFS to GPM Conversion?

The conversion between cubic feet per second (CFS) and gallons per minute (GPM) is essential in fluid dynamics and engineering applications. It allows for comparison and calculation of flow rates in different measurement systems.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( GPM \) — Gallons per minute
• \( CFS \) — Cubic feet per second
• \( 448.831 \) — Conversion factor (1 ft³/s = 448.831 gal/min)

Explanation: The conversion factor accounts for the volume difference between cubic feet and gallons, and the time difference between seconds and minutes.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for engineering designs, hydraulic calculations, water resource management, and comparing measurements from different systems.

4. Using the Calculator

Tips: Enter the flow rate in cubic feet per second (CFS). The value must be positive. The calculator will instantly provide the equivalent in gallons per minute (GPM).

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 448.831?
A: It comes from 1 cubic foot = 7.48052 gallons and 1 minute = 60 seconds (7.48052 × 60 ≈ 448.831).

Q2: When would I need to convert CFS to GPM?
A: Common in water supply systems, irrigation design, pump specifications, and when comparing data from different measurement systems.

Q3: How accurate is this conversion?
A: The conversion is mathematically exact, though practical measurements may have instrument-related uncertainties.

Q4: Can I convert GPM back to CFS?
A: Yes, by dividing GPM by 448.831 (CFS = GPM / 448.831).

Q5: Are there other related flow units?
A: Yes, such as liters per second (LPS) or cubic meters per hour (m³/h), each with their own conversion factors.
