Flow Rate Conversion Formula:
| From: | To: |
Flow rate conversion between gallons per minute (GPM) and cubic feet per second (CFS) is essential in hydraulic engineering, water management, and fluid dynamics. This conversion allows professionals to work with different measurement systems commonly used in various applications.
The calculator uses the conversion formula:
Where:
Explanation: The conversion factor is derived from the relationship between gallons and cubic feet, and minutes and seconds (1 gallon = 0.133681 cubic feet, 1 minute = 60 seconds).
Details: Accurate flow rate conversion is crucial for designing water supply systems, irrigation networks, hydraulic calculations, and environmental flow assessments. 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 compute the equivalent flow rate in cubic feet per second (CFS).
Q1: Why convert between GPM and CFS?
A: Different industries and regions use different flow rate units. Conversion ensures accurate communication and calculations across various applications and standards.
Q2: What is the conversion factor based on?
A: The factor is derived from volume and time conversions: 1 gallon = 0.133681 cubic feet and 1 minute = 60 seconds, so 1 GPM = 0.133681/60 = 0.002228 CFS.
Q3: When is GPM typically used?
A: GPM is commonly used in plumbing, HVAC systems, pump specifications, and residential water flow measurements in the United States.
Q4: When is CFS typically used?
A: CFS is often used in civil engineering, river flow measurements, large-scale water resource management, and environmental flow assessments.
Q5: Are there other common flow rate units?
A: Yes, other units include liters per second (LPS), cubic meters per hour (m³/h), and million gallons per day (MGD), each serving specific industry needs.
