About the mile and the kilometer
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.
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).
One mile equals 1.609344 kilometers, which makes the mile the longer unit of the two.
