GPM to CFS Conversion Formula:
| From: | To: |
GPM (Gallons Per Minute) to CFS (Cubic Feet Per Second) conversion is used to convert water flow rates between different measurement systems. This conversion is essential in hydrology, civil engineering, and water resource management.
The calculator uses the conversion formula:
Where:
Explanation: The conversion factor is derived from the relationship between gallons and cubic feet (1 cubic foot = 7.48052 gallons) and the time conversion (1 minute = 1/60 second).
Details: Accurate flow rate conversion is crucial for hydraulic calculations, pipe sizing, pump selection, and water distribution system design. Different industries use different units, making conversion essential for collaboration and standardization.
Tips: Enter the flow rate in gallons per minute (GPM). The value must be positive. The calculator will automatically convert it to cubic feet per second (CFS) with high precision.
Q1: Why convert between GPM and CFS?
A: Different engineering disciplines and regions use different units. GPM is common in plumbing and industrial applications, while CFS is standard in hydrology and civil engineering.
Q2: How accurate is the conversion factor?
A: The conversion factor 0.0022280092592591046 is highly precise, accounting for the exact relationship between US gallons and cubic feet.
Q3: Can this conversion be used for any liquid?
A: Yes, the conversion is based on volume and time units, so it applies to any fluid. However, the calculator assumes US gallons.
Q4: What are typical GPM values in practice?
A: Residential water systems: 5-20 GPM; Fire hydrants: 500-1500 GPM; Large water mains: 1000-5000+ GPM.
Q5: How does CFS relate to other flow units?
A: 1 CFS = 448.831 GPM = 0.0283168 cubic meters per second. CFS is commonly used for measuring river flows and large water systems.
