| From: | To: |
MGD (Million Gallons per Day) to CFS (Cubic Feet per Second) conversion is used in water resources engineering and hydrology to convert between two common units of flow rate measurement. This conversion is essential for water management, irrigation systems, and hydraulic calculations.
The conversion uses the formula:
Where:
Explanation: The conversion factor 1.547 is derived from the relationship between gallons and cubic feet, and the conversion between days and seconds.
Details: Accurate flow rate conversion is crucial for water system design, hydraulic calculations, irrigation planning, and environmental flow assessments. Different industries and regions use different units, making conversion essential for proper communication and calculation.
Tips: Enter the flow rate in MGD (million gallons per day). The value must be a positive number. The calculator will automatically compute and display the equivalent flow rate in CFS (cubic feet per second).
Q1: Why is the conversion factor 1.547?
A: The factor is derived from: 1 million gallons = 1,000,000 gallons = 133,680.56 cubic feet, and 1 day = 86,400 seconds. Therefore, 133,680.56 / 86,400 ≈ 1.547.
Q2: When is MGD typically used?
A: MGD is commonly used in water treatment plants, municipal water systems, and large-scale water distribution projects in the United States.
Q3: When is CFS typically used?
A: CFS is commonly used in hydrology, river flow measurements, irrigation systems, and hydraulic engineering calculations.
Q4: Are there other common flow rate units?
A: Yes, other common units include liters per second (L/s), cubic meters per second (m³/s), and gallons per minute (GPM).
Q5: How accurate is this conversion?
A: The conversion is mathematically exact based on standard unit definitions. The calculator provides results with 4 decimal places for precision.
