Customary/Imperial Unit

The mile is a measure of distance between two points used within the US Customary and British Imperial units of measure. It is customarily used to measure large geographical distances. The mile is officially defined as 5,280 feet, 1,760 yards or 1,609.344 meters. The abbreviation or for miles is 'mi' or sometimes 'm' as in miles per hour. The mile's origin stems from the Roman mile, which marked the distance the Roman army could march over 1,000 (mille) paces.

SI Unit

Within the SI (metric) system of measurement, the kilometer is officially defined as being equal to 1,000 meters. It is commonly used as measurement for geographic distances in similar circumstances where a mile would be used in the U.S. Internationally it is spelled 'kilometre' whereas the U.S. spells it 'kilometer'. The symbol for a kilometer is km however k is sometimes used.
