It is easy to understand why people on the other side of this big pond don't like metric system. Why complicate things, like one kilometer = 1,000 meters, one meter = 10 decimeters, one decimeter = 10 centimeters, one centimeter = 10 millimeters when you can have it simple using imperial measurements one mile = 5,280 feet or 1760 yards, one yard = 3 feet, one feet = 12 inches.
Even more complicated would be the mass and volume measures. Thank Goodness no one can force people to learn the complicated way like one kilogram = 1,000 gram and one liter = 10 deciliters, one deciliter = 10 centiliters, one centiliter = 10 milliliters when it's so much easier and more logical with one pound = 16 ounces or one gallon = 8 pints, one pint = 16 fluid ounces.
Not to mention how idiotic it is to say water freezes in 0 degrees and boils in 100. It's more logical to say freezing point is 32 degrees and boiling point 212.
