Road signs in the US and UK are in miles while most of the world uses kilometres. A 15-mile commute is 24.1 km, a 100-mile road trip is 160.9 km, and a 250-mile journey is 402.3 km. Running events, rental cars and fuel economy also cross units.
Do not use 1.6 for long distances: 1,000 mi is 1,609 km, not 1,600. The nautical mile is longer than the statute mile (1.852 km), so check which mile is meant.
The mile comes from the Roman mille passus, a thousand paces. The statute mile of 5,280 feet was set by an English Act in 1593 and became exactly 1.609344 km under the 1959 agreement.
