What is the difference between Kilometer and Miles?

A mile and a kilometer are both units of length or distance. Kilometers are used in the metric system and each one is about 6/10 of a mile, which is used in the US standard system of measurement. A mile is a unit of length or distance measurement that is equal to 5,280 feet.

Mile (land or statute mile) is an imperial system length unit and equals to 1760 yards, 5280 feet or 63 360 inches. 1 mile is about 60% longer than a kilometer.
