The metric system is used by almost every country in the world. There are only three countries that do not including the United States. The metric system uses a meters, liters and grams on a certain scale. Each step of the scale is a certain amount larger than the previous step. A kilometer is bigger than a mile. In the United States, they use miles to measure distance. Sometimes, there will be signs on the roads that display the number of miles and the numbers of kilometers away something is.
However, one kilometer equals to about 2/3 of a mile. It is actually a little less than 2/3, but it is close. A miles is equal to over two thousand feet.
