Convert km to miles
Please provide values below to convert kilometer [km] to mile [mi, mi(Int)], or vice versa.
Kilometer
Definition: A kilometer (symbol: km) is a unit of length in the International System of Units (SI). One kilometer is equivalent to 0.6214 miles.
History/origin: The prefix kilo- is a metric prefix indicating one thousand. One kilometer is therefore one thousand meters. The origin of the kilometer is linked to that of the meter, and its current definition as the distance traveled by light in 1/299 792 458 second. This definition is subject to change, but the relationship between the meter and the kilometer will remain constant.
Current use: It is currently the official unit of measurement for expressing distances between geographical places on land in most of the world. However, there still remain a number of countries that primarily use the mile instead of the kilometer including the United States and the United Kingdom (UK). Unlike the United States, the UK has adopted the metric system; while the metric system is widely used in government, commerce, and industry, remnants of the imperial system can still be seen in the UK's use of miles in its road systems.
Mile
Definition: A mile (symbol: mi or m) is a unit of length in the imperial and US customary systems of measurement. It is currently defined as 5,280 feet, 1,760 yards, or exactly 1,609.344 meters.
History/origin: The mile is an English unit (predecessor of Imperial units and United States Customary Units) of length. The use of the abbreviation "m" for mile was common before the widespread adoption of the metric system; after the adoption of the metric system, "mi" became the preferred abbreviation in order to avoid confusion between miles and meters. The definition of a mile as 5,280 feet (or 8 furlongs), sometimes referred to as the statute mile, international mile, or land mile, which differs from the Roman mile of 5,000 feet, developed due to the importance of the furlong in England, back in 1593. There also exist a number of units based on, or closely related to, the Roman mile, including the nautical mile (1.852 km exactly), Italian mile (~1.852 km), and the Chinese mile (500m exactly).
Current use: Although most countries have adopted the metric system and use kilometers, rather than miles, to express land distance, the mile is still prevalently used in countries such as the United States (US), United Kingdom (UK), Myanmar, and Liberia, as well as some other countries which are either US or UK territories, or have historical ties with either country.
