Two liters is equal to approximately 67.62 oz. of Pepsi. The average 2 liter is made to supply eight servings of 8 oz. cups.
Although a Pepsi 2 liter nutritional label states that each bottle provides eight servings, the approximate amount of ounces available leaves room for just over an extra half cup of soda.
American soda companies use metric sizing for soda bottles. A 1 liter soda bottle houses 33.31 oz. of soda, while each can holds approximately 12 oz. Some distributors manage to sell 3 liter bottles, which hold just over 100 oz. of soda. Russia has alternate sizes available, ranging between 1.5 and 2.5 liters or 50.72 to 84.53 oz.
