A comment on: The Chinese round everything to a round metric size before manufacturing and the American consumer is totally .....
The Chinese are not that dumb to waste their time on duplicated converting and risking a mistake. They sure know which hardware is made to one and only internationally accepted standard (ISO, DIN, SAE, ..) and that they must make the product to conform to sell. The socket wrench drive is one of many such products standardized with also metric sizes and tolerances. They fall into the "metric" category of "globally prevalent practice" to use my terminology. I like your naming the drives small, medium and large as that is indeed how we referred to them on Europe (large and small to be exact because I only had two sizes). The same, as an example, with the spark plug wrench - never by its size only by the name "s. p. wrench." There used to be only one size, so today, I presume, that also are called, maybe, tiny and ordinary.

Turns out the 10 mm and 13 mm are quite common bolt/nut sizes.
