For example, a "9 mm pistol" has a barrel diameter of about 9 millimeters. Barrel diameters can also be expressed using metric dimensions. For example, a "45 caliber" firearm has a barrel diameter of roughly 0.45 inches (11 mm). In the United States it is expressed in hundredths of an inch in the United Kingdom in thousandths and elsewhere in millimeters. It is measured in inches or in millimeters. In guns, particularly firearms, caliber (or calibre sometimes abbreviated as " cal") is the specified nominal internal diameter of the gun barrel bore – regardless of how or where the bore is measured and whether the finished bore matches that specification.
