In the imperial measurement system, an inch is a unit of length used mainly in the United States and some other nations. Defined as exactly 25.4 millimeters, the inch has historically been a common measurement unit, with its length differing slightly across cultures. The current standard inch, as defined in the 1959 international yard and pound agreement, is one-twelfth of a foot. Inches are widely used in construction, for sizing screens on electronic devices, and for fabric measurements in the textile industry. They are also used to measure human height in countries where the imperial system is in use.
