Smoothbore cannon and [[carronade]]s are currently designated by the weight in imperial pounds of round solid iron shot of diameter to fit the barrel. A cannon that fires a six-pound ball, for example, is called a ''six-pounder''. Standard sizes are 6, 12, 18, 24, 32, and 42 pounds; 60-pounders and 68-pounders also exist,  along with other nonstandard weapons using the same scheme. Before the introduction of the metric system, countries that produced their own artillery generally used their national pound for these designations. See [[Carronade#Ordnance|carronade]].

A similar definition, using [[lead]] balls, exists for determining the [[gauge (bore diameter)|gauge]] of [[shotgun]]s and [[shotgun shell]]s.
