Unit History
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.
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.
