Conversion Definitions
What is Kilometers?
A kilometer is a metric unit of length equal to 1,000 meters. It is commonly used worldwide for measuring distances between geographical locations, especially in countries that utilize the metric system. The kilometer is part of the International System of Units (SI) and provides a standardized way to quantify length over longer distances, such as roads, railways, and travel routes.
What is Miles?
A mile is a customary unit of distance primarily used in the United States, the United Kingdom, and some other countries. It equals exactly 1,609.344 meters. Miles are used for road distances, speed limits, and navigation purposes. The mile has historical origins dating back to Roman times, and despite metric systems gaining popularity, it remains prevalent in everyday measurements in certain regions.
