An inch, a unit of length in the imperial system, is predominantly used in the United States and several other nations. Defined as 25.4 millimeters, the inch has varied slightly in length in different cultures historically. Under the 1959 international yard and pound agreement, an inch in the imperial system is one-twelfth of a foot. Inches are commonly used in construction measurements, electronic device screen sizes, and fabric dimensions in the textile industry. They are also used to measure individual heights in countries that follow the imperial system.
