Two different meanings for firearms. For artillery, caliber is the relation of the diameter of the bore to the length of the barrel. A gun on a Navy Destroyer might be known as a 5 inch 38 caliber- meaning it fires a 5 inch diameter shell, and the barrel is 38 times 5 inches long. However, for rifles and handguns, it means the fractions of one inch that equal the diameter of the bore. So a .30 caliber rifle has a bore than measures ABOUT .30 inches, a .50 caliber ABOUT .50 inches, and so on. Some firearms have measurements from the metric system- a 9millimeter pistol has a bore diameter of ABOUT 9mm.
