Unit History
About kilometers
The kilometer was established following the definition of the meter, representing exactly 1,000 meters. It quickly became a standard for measuring longer distances, such as those between cities or geographic landmarks. Most countries that use the metric system rely on kilometers to indicate road and travel distances.
About light years
A light-year, though not part of the SI system, is a common astronomical unit used to express vast distances in space. It came into broader usage after scientific measurement of the speed of light in the 19th century. Scientists and educators often use light-years to help illustrate the immense scales between celestial objects, offering a more tangible sense of distances in the universe.
