What is the MGD equivalent of 678,000 gallons?

To determine the million gallons per day (MGD) equivalent of 678,000 gallons, you need to convert gallons to MGD by understanding the conversion factor.

One million gallons is equal to 1,000,000 gallons. Therefore, to convert 678,000 gallons to MGD, you divide the total gallons by 1,000,000:

[

\text{MGD} = \frac{678,000 \text{ gallons}}{1,000,000 \text{ gallons/MGD}} = 0.678 \text{ MGD}

]

This calculation shows that 678,000 gallons translates to 0.678 MGD, making it the correct answer. Understanding this conversion is crucial for water treatment operators, as they often need to work with different units of measurement for water flow rates and capacities.
