Inch

What is inch?

Inch is the smallest unit of length in the US customary system. The unit derives from the Old English ince, or ynce, which in turn came from the Latin unit uncia, which was “one-twelfth” of a Roman foot, or pes.

The inch is a commonly used customary unit of length in the United States, Canada, and the United Kingdom. It is also used in Japan for electronic parts, especially display screens. In most of continental Europe, the inch is also used informally as a measure for display screens.
