Miles (mi) to Kilometers (km) Conversion
Miles
The mile is a unit of length with roots in the Roman mille passuum ("thousand paces"), approximately 1,480 metres. The modern international mile, standardised in 1959, is defined as exactly 1,609.344 metres. It remains the primary unit of road distance in the United States, United Kingdom, and a small number of other countries, and is used in aviation for visibility reporting. The statute mile should be distinguished from the nautical mile (1,852 m), used in maritime and aerial navigation worldwide.
Kilometers
The kilometre, equal to exactly 1,000 metres, is the standard unit for measuring distances at a geographic and infrastructural scale, including road distances, flight paths, and the dimensions of countries and continents. It is derived directly from the metre by applying the SI prefix kilo- (from Greek khilioi, meaning thousand) and is universally used in science, meteorology, and everyday life in all countries that have adopted the metric system. The Earth's circumference at the equator is approximately 40,075 km, a value historically used in the original derivation of the metre itself.
