Talk:12-pounder long gun

define 12 (or any other) pounder in modern units edit

It's probably the case that a 12 pounder is the caliber or bore size, but pounder is an anglicized version of the french livre which in it's time was about 489.5 grams, the standard varied depending on which town or country. Units of measurement in France before the French Revolution. How is the modern reader in a metric country with no knowledge of pounds supposed to approximate what this would be in modern units of mass? I'm assuming the bore had a relationship to the mass of an iron cannon ball. I'm thinking roughly 6 kg as the french livre would give a mass of 5.87 kg.
