Is the term “caliber” proper here? I assume it is a 6.8mm round. I am used to hearing “caliber” referred to as inches.
Am I old fashioned? Did I miss the metric conversion of everything?
Just to muddy the waters a bit more, the length of naval guns are measured in calibers, as in 5”, 50 caliber, a 5” gun that is 250” long.
At least that’s how an ANGLICO Marine explained it to me at an FDC course.
