The CFS to GPM conversion calculates flow rate from cubic feet per second to gallons per minute. This conversion is essential in hydraulic engineering, water management, and fluid dynamics applications where different measurement units are used.
The calculator uses the conversion formula:
Where:
Explanation: One cubic foot equals approximately 7.48052 gallons, and one minute contains 60 seconds. The conversion factor (7.48052 × 60 = 448.8312) accounts for both volume and time unit conversions.
Details: Accurate flow rate conversion is crucial for engineering design, irrigation systems, water treatment plants, and industrial processes where precise flow measurements are required across different unit systems.
Tips: Enter the flow rate in cubic feet per second (CFS). The value must be positive. The calculator will instantly convert it to gallons per minute (GPM).
Q1: Why is the conversion factor 448.8311688312?
A: This factor comes from multiplying gallons per cubic foot (7.48052) by seconds per minute (60), resulting in 7.48052 × 60 = 448.8312.
Q2: 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 major dams can handle 10,000+ CFS.
Q3: When would I need to convert CFS to GPM?
A: Common in water supply systems, hydraulic calculations, pump specifications, and when comparing flow rates between metric and imperial systems.
Q4: Are there limitations to this conversion?
A: The conversion is mathematically exact for pure water under standard conditions. For other fluids, density variations may require adjustments.
Q5: How accurate is this conversion?
A: The conversion is mathematically precise. Accuracy depends on the precision of your input measurement and the calculator's rounding.
