Milk has traditionally been sold in the U.S. in pints, quarts and gallons, a custom that seems destined to stay. There are many products measured in metric only (or primarily) besides soda in the U.S. But since lots of American products are sold overseas, you'll usually see both types of measurements on the packaging.
