A gallon is a unit of measurement that is larger than a quart, pint, and cup. You may want to present to your children with an empty gallon carton of milk or a gallon soup pot. With some assistance they can pour 4 quarts into the gallon container to understand that 4 quarts are equal to 1 gallon.
Then the whole world (except the US) went metric, and the standard sizes in the metric system were adopted by bottle making, water, and soda companies. Conveniently, 1 liter, is just a little bit larger than a quart. That is, a normal (standard 1/2 liter) bottle holds just over 2 cups of water. The difference between a half liter and a pint is so small that most people donât worry about it. A glass of water is considered to be 8 ounces, or one cup, though most glasses are, in practice, larger. So if you are following a recommendation to drink 8 or 12 cups of water a day, that would be 4 or 6 bottles.
