The '''7.62&nbsp;mm caliber''' is a nominal [[caliber]] used for a number of different [[cartridge (weaponry)|cartridges]]. Historically, this class of cartridge was commonly known as '''.30 caliber''', the equivalent in [[imperial unit|Imperial]] and [[United States customary unit|United States Customary]] measures. It is most commonly used in hunting cartridges. The measurement equals 0.30 inches or three [[Line (unit)|decimal lines]], written '''''.3″''''' and read as '''''three-line'''''.<ref>Holt Bodinson: [https://www.thefreelibrary.com/The+old+Three-Line%3A+still+a+great+value.-a0151841457 The old Three-Line: still a great value], Guns Magazine, Nov, 2006</ref>

The 7.62&nbsp;mm designation refers to the internal diameter of the barrel at the lands (the raised helical ridges in rifled gun barrels). The actual bullet caliber is often {{convert|7.82|mm|abbr=on}}, although Soviet weapons commonly use a {{convert|7.91|mm|abbr=on}} bullet, as do older British ([[.303 British]]) and Japanese ([[7.7×58mm Arisaka]]) cartridges.
