About the kilometer and the mile
A kilometer (kilometre) is 1,000 meters and the standard road-distance unit in most countries. A brisk walker covers about 5 km in an hour, and popular race distances are 5 km, 10 km, the half marathon (21.0975 km) and the marathon (42.195 km).
The statute mile equals 5,280 feet. It is the official road-distance unit in the United States and United Kingdom, where speed limits are posted in miles per hour, and it is also used in running and aviation contexts.
One mile equals 1.609344 kilometers, which makes the mile the longer unit of the two.
