Ok, What ia half of 5.3 mm?

It's 2.65mm.

Jaysus! If you can't divide 5.3 by 2 in your head, you just flunked
gradeschool math.

Now that you have told me the answer, point me to a rule that will
indicate that distance.

I work with metric these days. Frankly, in 20 years I've never seen
anything 5.3mm called out. Nor have I seen .20866 inches. (Quick, what is
half of that?)

One of the beauties of the system is things tend to be more whole numbers
rather than 21/64 and 17/32. There is no logical reason that we could not
comfortably change and use metric other that we don't want to change. The
rest of the world manages to build some rather complex and sophisticated
machines with it and I bet we could too.
