The inch is a traditional unit of length used in the United States, United Kingdom, and Canada. While many countries have moved to the metric system, the inch remains vital in industries like screen manufacturing, tire sizing, and tool engineering. Since 1959, the inch has been tethered to the metric system by an exact definition.
