Gun calibres?

If you work in SI you don't have to do conversions. And it is so much simpler.
I'm a crotchety old git and old enough to have learned Imperial.
I used to think in Imperial and mentally convert to SI.
Now, I'm pretty much bilingual.
My 50mm by 6.3mm bus bar is about two by quarter in inches.

Well, if the metric diameters had been listed first then it would have been "calibres"

However, since the inch diameters were listed first, its "gun calibers".

The context was a lucky guess on my part. We don't much do guns here*.

The difference between British English and US English has not a lot to do with it.
SI is used in almost all of the countries in the world regardless of the language used. Whether calibre or caliber.

*Of some relevance to the original topic, we buy transformers, complete with bus bars, from a supplier based in what was a BSA location.
The BSA name is most often associated with the motor cycles with that name. But the initials stand for Birmingham Small Arms. And that's what they did.

Below is a pic of one of their transformers. The bus bar at the bottom was copper and two 200mm by 12.5mm in parallel giving a rating in free air of about 8kA.
