A '''cubic mile''' (abbreviation: '''cu&nbsp;mi''' or '''mi<sup>3</sup>'''<ref>[http://physics.nist.gov/Pubs/SP811/appenB8.html NIST Guide to the SI - B.8 Factors for Units Listed Alphabetically]</ref>) is an [[Imperial unit|imperial]] and [[United States customary unit|US customary]] (non-[[SI]] non-[[Metric system|metric]]) unit of [[volume]], used in the United States, Canada and the United Kingdom. It is defined as the volume of a [[cube]] with sides of {{convert|1|mi|km|lk=on}} length, giving a volume of {{convert|1|mi3|km3}}.
