Why are shafts sizes metric??

I'm just guessing, but I would think that perhaps pool was invented in Europe or Asia or something, and not here in the US where we made up our own nonsense measurements.

Lol, we didn't make up our own nonsense measurements. Sure seems that way sometimes, though.
The imperial system was created by the British Bureau of Standards and was the world standard until the metric system was created by the French. We simply haven't completely adopted it....yet.
I think it has something to do with which part of the cue can go bad first. Just imagine while in Europe or Asia and you need a tip replacement. If any part of the shaft goes bad, you probably need a new cue anyways.
Hmm, I didn't think about the shaft length and weight measurements... That is rather odd that it's mixed. Oh well, I guess I have no idea!

Most of the best cues are still made in the US, but they probably adopted a metric tip measurement for eventual replacement.
I can't tell you WHY the metric system is being used to specify shaft o.d. but I can tell you HOW its the better choice.
A shaft is typically specified by the 1/4 mm...as in 12-3/4 mm. Each 1/4mm is almost 0.001 inches or 1/1000 inch...a very small incremental change.
If we were to use english units, we would probably go with 64ths of an inch. Each 1/64 inch is about 0.016 inches...a very big incremental change.
As in most cases, the english system is too coarse.
Edit: Per the Bureau of Engraving and Printing, the thickness of a dollar bill is approximately 1/10th of a mm or 1/250th of an inch.

In machining (atleast in America) we measure everything in thousandths.. I.E. .001 being 1 thousandth of an inch. Believe me I wish cues were measured in standard it'd make things so much easier. If you measure a cue with a pair of calipers (std) and come up with .514 on the tip.. Well then it's .514, what the hell is that in MM? I dunno let me get my calcultor. What if I want my tip to be .520 thousandths? etc.. etc..

Now, you know that you need to get caliper in metric.
Just another reason why pool wouldn’t succeed, we can even describe the dimensions of a cue consistently. Good question though. Hell I’m 6 ft 1 mm tall.
C'mon Yankees get into the program switch to metric system.

roughly......
.514=13.06mm
.520=13.21mm

the older ones were a bit thinner.......
