[CAUT] Wire gauge question

[Zeno Wood]

Ok, what's going on here?  Would a Yamaha CFIII be using a different
system of wire gauge?  It says 14 or 14.5 on the bridge, but it
measures more like .032" which is 13.5 - is this metric?  If so, whose
idea was it to make metric and "normal" so close to each other?

Thanks,
scratchin' my head...
