About Millimeter


Definition: A millimeter, denoted as mm, constitutes a unit of length within the International System of Units (SI). It is precisely defined as 1/1000th of a meter, which corresponds to the distance that light travels in 1/299,792,458,000 of a second.
History/origin: The "milli-" prefix is one of numerous metric prefixes, signifying a division by one thousand of the base unit, the meter, in this instance. Although the definition of the meter has undergone modifications over time, the relationship between the meter and the millimeter remains constant. Previously, the meter was defined based on the length of a prototype meter bar. However, in 2019, the meter was redefined to align with changes made to the definition of a second.

About Inch


Definition: An inch, represented as "in," serves as a unit of length in the imperial and US customary systems of measurement. The inch was officially determined to be precisely equal to 25.4 millimeters in 1959. There are 12 inches in a foot and 36 inches in a yard.
History/origin: The term "inch" derives from the Latin word "uncia," which equated to "one-twelfth" of a Roman foot. Throughout history, various standards for the inch have existed, with the contemporary definition being based on the international yard. One of the earliest definitions of the inch was based on the length of barleycorns, where an inch corresponded to the length of three grains of dry, round barley arranged end-to-end. Another iteration of the inch is believed to have been derived from the width of a human thumb, calculated as an average of three thumb widths: a small, medium, and large thumb.
Current use: The inch is primarily utilized in the United States, Canada, and the United Kingdom. It is also occasionally employed in Japan, along with other countries, particularly in the context of electronic components, such as display screen sizes.
