Unit History
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.
About millimeters
The millimeter, one-thousandth of a meter, emerged from the metric system's emphasis on decimal subdivisions. Due to its small size, it is essential for precision in engineering, manufacturing, and carpentry. Millimeters help ensure fine tolerances are met in fields ranging from automotive parts to delicate consumer electronics.
