Kílómetra

Kílómetra is the Greek word for kilometer. A kilometer is a unit of length in the metric system, equal to one thousand meters. It is equivalent to approximately 0.621371 miles. The kilometer is the standard unit for measuring distances on land in most countries worldwide. Its definition is based on the meter, which is currently defined as the distance light travels in a vacuum in 1/299,792,458 of a second. The prefix "kilo" signifies a factor of one thousand, so a kilometer is 1000 meters. This unit is commonly used for everyday measurements such as road distances, travel distances, and the length of rivers or mountain ranges. In scientific contexts, the kilometer is also used, though the meter is the base unit. The abbreviation for kilometer is km.
