I'm sorry. There were two (or more points) discussed. I fixated on one of them, and ignored the others, when I saw the point made.
In post #49 You stated:
100 caliber = 1 inch or 25.4 mm
360 millimeters = 14.173228 inches
360 millimeters = 1417.3228 caliber
When I saw that, I assumed you were implying that the "caliber" of a 14 inch Naval Cannon is 1417. It is not.
(The site you linked in post #49 is a brainless conversion calculator. Caliber was defined in that code as 100 to 1 inch. But that is not the only way the word "caliber" is defined.)
I have never seen a 14 inch Naval gun refered to as a "1417 caliber" weapon. Ever.
There are many reference works that list Naval cannon (of the same bore size) by barrel size and weight.
Naval gun tables references:

As I tried to point out, anytime the word "calibre" when used
in the context of a (usually larger than 5 inch) naval gun, the "caliber" rating is the length of the barrel, as Jeff says in post #58.
I realise that small arms (like the "30 aught 6" you mention, caliber
is a measurement of bore. I wasn't (and never have been) talking about small arms.
Which shows you and Jeff both jumped to unfounded conclusions.
