Understanding CFS to MGD Conversion

Converting cubic feet per second (CFS) to million gallons per day (MGD) is essential for water resource management, wastewater treatment, and municipal water supply planning.

Conversion Formula

The formula to convert CFS to MGD is:

$$\text{MGD} = \text{CFS} \times 0.538171$$

Where:

  • CFS = Flow rate in cubic feet per second
  • MGD = Flow rate in million gallons per day
  • 0.538171 = Conversion factor

Example Calculation

Convert 7 CFS to MGD:

$$\text{MGD} = 7 \times 0.538171 = 3.77 \text{ MGD}$$

Common Applications

  • Water Treatment Plants: Sizing treatment capacity
  • River Flow Measurements: Converting hydrological data
  • Irrigation Systems: Planning water distribution
  • Wastewater Management: Determining treatment requirements
