7.62 mm caliber is a nominal caliber used for a number of different cartridges. Historically, this class of cartridge was commonly known as .30 caliber, the Imperial unit equivalent, and was most commonly used for indicating a class of full power military main battle rifle (MBR) cartridges. The measurement equals 0.30 inches or 3 decimal lines, written .3" and read as Three-Line.

The actual bullet caliber is normally 7.82 mm (.308 in), although Soviet weapons commonly use a 7.91 mm (.311 in) bullet, as do older British (.303 British) and Japanese cartridges.
