Calculation

Kilometers

Kilometers are a unit of length in the metric system, representing one thousand meters. They are commonly used for expressing longer distances, such as travel distances between cities or countries. The kilometer became widely adopted as part of the metric system's introduction during the late 18th century.

Lightyears

A light-year is a unit of astronomical distance, and it represents the distance that light travels in one year through the vacuum of space. Light travels at a speed of approximately 186,282 miles per second (299,792 kilometers per second) in a vacuum. The light-year is commonly used in astronomy to measure distances on a cosmic scale because of the vast distances involved in space. For example, the distance to nearby stars, galaxies, and other celestial objects is often expressed in terms of light-years due to the impracticality of using more familiar units like kilometers or miles for such immense distances.
