What is Cubic inch?
[[File:Chevy502CID.jpg|thumb|An engine size noted as 502 cubic inches]] The '''cubic inch''' is a [[unit of measurement]] for [[volume]] in the [[Imperial units]] and [[United States customary units]] systems. It is the volume of a [[cube]] with each of its three [[dimension]]s (length, width, and depth) being one [[inch]] long. The cubic inch and the [[cubic foot]] are still used as units of [[volume]] in the [[United States]]. One popular use is for [[Engine|engine capacity]], also called cubic inch displacement.<ref>Richard Feldman, ''Transportation Expressions (1996)'' (US Department of Transportation, 1996), p. 64</ref> The common [[International System of Units|SI]] units of volume, the [[liter]], [[milliliter]], and [[cubic meter]], are also used, especially in [[manufacturing]] and high technology. One cubic foot is equal to exactly 1,728 cubic inches because 12<sup>3</sup> = 1,728. One cubic inch equals 16.39 cubic [[centimeter]]s.<ref>{{cite web |url=http://www.businessdictionary.com/definition/cubic-inch-cu-in-or-in3.html |title=cubic inch (cu in or in3) |publisher=WebFinance, Inc |access-date=7 January 2016 |archive-date=12 January 2016 |archive-url=https://web.archive.org/web/20160112201120/http://www.businessdictionary.com/definition/cubic-inch-cu-in-or-in3.html |url-status=dead }}</ref> == References == {{reflist}} [[Category:Imperial units]] [[Category:Units of volume]]
