How many fluid ounces are in one liter?

1 liter = 33.8140226 US fluid ounces

1 US fluid ounce = 0.0295735297 liters

Note that this is for fluid ounces, not dry ounces. A fluid ounce is a measure of volume, just like a liter is. A dry ounce is a measure of weight. The weight of one liter of a substance depends on its density. So it depends on what you are measuring. One liter of lead weighs a lot more than a liter of feathers!

1 liter = 1000 ml

One 12 ounce can of pop contains 355 ml, so three 12 ounce cans of pop would be 1 liter plus 60 ml.

Please note that "liter" is spelled "litre" in the U.K.
