How Many Ounces in a Liter of Water
Assuming you’re talking about US customary units, a liter of water is 33.8 ounces. This is because a liter is defined as the volume of one kilogram of water, and a kilogram of water is 1000 grams. There are 28.35 grams in an ounce, so 1000 grams divided by 28.35 equals approximately 35.2 ounces (it’s actually a bit more than that, but we’ll round down for simplicity).
One liter is equal to 1000 milliliters, so 33.8 ounces is also equal to 1000 milliliters (or 1 cubic decimeter).
