I realize the British used the weight of a round to designate a weapon system (25 pounder, 18 pounder, etc). Can someone direct me to a source that specifies of how to translate pounds to millimeters?
thanks

Hi DJ
I presume you want to know what the actual calibre of these guns were. Here's four of the most common:
25 pounder - 87.5mm
18 pounder - 84mm
17 pounder - 76.2mm
6 pounder - 57mm
I hope they're of some use to you.

Dave-- that's what I am looking for....is the Comet 77mm main gun also a pound type designation?
thanks again

This should answer your question. Quote from Wikipedia:

The tank designers opted to use a highly modified version of the 17 pounder, the 77 mm (despite the fact that it was still of the same 76.2mm calibre as the 17 pdr it was named the 77mm because it used different and non-interchangeable ammunition to the 17 pdr) that had a lower muzzle velocity than the O.Q.F 17-pdr.

You cannot 'translate' pounds into millimeters unfortunately, all you can do is to discover the actual barrel diameter for each type.
