10. MEASUREMENTS Europeans: Europe uses the metric system. If you can multiply by 10, you now have the next highest unit. Boom. Done.
Americans: There are 3 teaspoons in a tablespoon, 16 tablespoons in a cup, 2 cups in a pint, 2 pints in a quart and 4 quarts to a gallon. There are 12 inches in a foot, 3 feet in a yard and 1,760 yards in a mile (or 5,280 feet, as is more commonly known). There are 144 square inches in a square foot and 43,560 square feet in an acre. There are 16 ounces in a pound and 2,000 pounds in a ton. This list excludes such fun units as picas, furlongs, fathoms, nautical miles, survey townships, bushels and hogsheads. Yup. A hogshead is a unit of measurement and not a Harry Potter character. Look it up.
