The inch, a length unit in the imperial system, is mainly utilized in the United States and several other nations. An inch is officially 25.4 millimeters. Throughout history, the inch has served as a customary unit in various cultures, with minor variations in its length. The current standard inch, as per the 1959 international yard and pound agreement, is based on the imperial system and is one-twelfth of a foot. In everyday applications, inches are used for construction measurements, electronic device screen sizes, and in textiles for fabric measurements. They are also commonly used to measure human height in imperial system-dominant countries.
