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 follow the metric system. Kilometers are part of the International System of Units (SI) and are used in navigation, travel, and mapping contexts.
What is miles?
A mile is a unit of distance traditionally used in the United States and the United Kingdom, equivalent to 5,280 feet or approximately 1,609.34 meters. Miles are frequently employed for measuring road distances, speed limits, and travel times in countries that do not primarily use the metric system.
