<span>1 Liter = 1.05 quart.
1/1.05 Liter = 1.05/1.05 quart = 1 quart.
Replacing this value of quart in the equation below.
1 gallon = 4 quarts
1 gallon = 4 * 1/1.05 Liters
1 gallon = 3.80952380952
Total oil consumption per year in gallons is 600,000,00
So, total oil consumption per year in liters is obtained by:
600,000,000 * 3.80952380952 = 2285714285.71 liters
Converting to scientific notation, we have 2.28571 * 10^9 liters.</span>
