Conversion Definitions

What is kilometers?
A kilometer is a metric unit of length equal to 1,000 meters. It is commonly used worldwide to measure distances in transportation, geography, and everyday life. The kilometer’s adoption as part of the metric system makes it a standard unit in most countries, especially outside the United States, where miles are more prevalent.

What is miles?
A mile is an imperial unit of length primarily used in the United States and the United Kingdom. It equals 1,609.344 meters and is employed to measure distances on roads, in sports, and in various navigation contexts. Miles have historical roots in the Roman ‘mille passus,’ meaning ‘a thousand paces.’
