What is INCHES

The inch (abbreviation: in) is a unit of length in the (British) imperial and United States customary systems of measurement. There are 12 inches in a foot and 36 inches in a yard. During the 1950s and 1960s it has been based on the metric system and defined as exactly 2.54 cm. It is equal to 1⁄36 yard or 1⁄12 of a foot. Derived from the Roman uncia ("twelfth"), the word inch is also sometimes used to translate similar units in other measurement systems, usually understood as deriving from the width of the human thumb.

The inch (in) 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. For the United Kingdom, guidance on public sector use states that, since 1 October 1995, without time limit, the inch (along with the foot) is to be used as a primary unit for road signs and related measurements of distance (with the possible exception of clearance heights and widths) and may continue to be used as a secondary or supplementary indication following a metric measurement for other purposes.

Did You Know?

The ancient Romans used a system of weights and measures based on units divided into 12 parts. In this way the Latin uncia, meaning “a 12th part,” designated the 12th part of a foot. From this is derived Old English ince or ynce and modern English inch. The Roman pound was also divided into 12 parts, similarly designated by the word uncia. In this sense uncia followed a different path and became Middle English unce or ounce, which was the 12th part of a pound in the troy system. In the avoirdupois system, which is more widely used, the pound is larger and equals 16 ounces. The English noun inch dates to before the 12th century; the verb meaning “to move very slowly” does not appear until around 1600.
