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!
