The metric system includes a set of decimalized units such as kilogram (Kg), meter (m) or second (s) used internationally to measure different variables such as weight, energy, time or distance. The purpose of this system is to guarantee all around the world people use the same units and therefore measurements can be understood and used by everyone. For example, in trade, a kilogram of cheese represents the same amount of cheese all around the world. According to this, it is false the metric system is used exclusively in the United States because the main purpose of this is that is used all around the world.
