How Much is One Liter?

Well how much is one liter in relation to what? The easiest way to figure out how much is one liter is to convert it into a measurement that perhaps you use more often such as a cup. So if you were to drink 4.23 cups of water then you would have drank about a liter of water. Another way to think of it would be if you drank half of a 2 liter bottle of soda.
