Gun measurements request

I like the idea of converting everything to the metric system, when the Japanese used it historically. Makes things more clear to me.

That's because it is a shell's energy that we should be most interested in, not its diameter

That's only true if you are not interested in high explosive. If you are interested in HE, energy has nothing to do with lethality. The British system, however, does not measure energy, since energy is a function of the weight and the square of the speed. Weight mattters, but velocity matters more.

The US used the "pound system" during the American Civil War and the plains and SW campaigns through the 1880s. I figure the UK was still using pounds only because they were preserving something anachronistic.

The 2 pounder was approx 40mm, the 6 pounder was approx 57mm, the 17 pounder was approx 76-77mm, and the 25 pounder was approx 85mm (not as certain on the last one)

I know how to convert, and everything,
25.4mm or 2.54cm =1"
76.2mm = 3", etc., etc.

But it is a pain in the a$$ to figure out the many variations on the 4 - 8 inch range of guns. so I'd much rather not have to.

Of course the British had the screwiest system of all:

Does anyone know the bore of the 2 pounder, 6 pounder, 17 pounder and 25 pounder??

(of course i know, just testing you all (there were 2 different 17 pounders made too))
