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 inches
The inch, once based on the width of a human thumb, is now precisely 2.54 centimeters. Alongside feet, it remains common in the US, Canada, and the UK for many small-scale measurements, such as monitor screens, tool sizes, and parts in home-improvement stores. Its standardized conversion makes it simpler to toggle between customary and metric systems.
