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 amount of glasses of water in a liter depends on the size of the glass. An 8 ounce glass is equal to just under 1/4 of a liter, which means that just over four 8 ounce glasses of water is equivalent to 1 liter. If the glass is measured in cups, 3 liters equals about 13 cups of water. This means that 1 liter would be about 4 1/3 cup size glasses of water. Two 16 ounce bottles of water would equal 1 liter, and it would take about six 6 ounce glasses of water to reach 1 liter. Learn more about Food Measurements
