How Many Ounces Are in a 2-Liter Bottle?

One liter is 33.814 fl oz, so multiply the liters by 33.814 to get US fluid ounces. For a two-liter bottle, that is 2 × 33.814 = 67.63.

To go the other way, divide fluid ounces by the same number, or use the ounces to liters converter. The UK (imperial) fluid ounce is slightly smaller, 28.41 ml instead of 29.57 ml, so the count in imperial ounces comes out higher.

In US measure, two liters is 8.45 cups, 4.23 pints or 2.11 quarts. That makes a two-liter bottle a little more than half a US gallon, which is 1.893 L.

Metric cups divide more evenly. A metric cup holds 250 ml, so a two-liter bottle fills exactly 8 of them.

Filled with water, the contents weigh about 2 kilograms, or 4.41 pounds, based on USDA data for water. Add the weight of the bottle itself on top of that.

The figure is for plain water, so other drinks can differ slightly. For other amounts, use the liters to kilograms converter.

Coca-Cola's US site lists Coca-Cola Original in sizes from 7.5 fl oz up to 1.25 L and 2 L. The two-liter is the largest size on that list, and the 1.25 L bottle holds 42.27 fl oz.

The single-serve bottles are much smaller. Coca-Cola counts its whole 20 fl oz bottle as one serving, and its convenience-store lineup also includes a 24 fl oz bottle, according to a 2025 company release.

Water comes in liter sizes too. Dasani lists a one-liter bottle of 33.81 fl oz, and Poland Spring lists a three-liter bottle of 101.4 fl oz.

Divide the bottle's fluid ounces by the size of one serving. The table below does the math for several glass and bottle sizes.

Four 16.9 fl oz bottles, which hold half a liter each, add up to one two-liter bottle. Ice changes the count: a glass full of ice holds less soda, so the bottle pours more glasses than the table shows.
