very nice..
but ...please, what the hell is anything like   "19/32"    !!!! ?

an example of one place metric makes a whole lot more sense !

looks like you missed 9/16th's and 14mm.

a 14mm is a quite tight 9/16th's, and a 9/16 is a very loose 14mm.
once in a while that is useful to know.

and 23mm..
I have never found one of those on any vehicle ever..
21, 22, and 24 yes...
but 23 ..no way !
and something like 19/32 .............I BETTER not be looking for anything
like that !
lol.
