The inch, a unit of length in the imperial system, is mainly employed in the United States and several other regions. Defined as precisely 25.4 millimeters, the inch has historically varied in length across different cultures. As per the international yard and pound agreement of 1959, an inch in the imperial system is one-twelfth of a foot. Inches are commonly used for practical measurements in construction, screen sizes of electronic devices, and fabric dimensions in the textile industry. They are also used to measure human height in imperial system-dominated countries.
