whether a stone is 12, 13 or 14 pounds. I still tend to forget.

Just remember the "98 pound weakling" trope.  Seven stone exactly,
49*2.

My brain's already storing facts like 12 inches per foot, 36 inches
per yard, 5280 feet in a mile, 88 ft/s = 60 mph, 231 cubic inches per
gallon, 43560 square feet per acre etc. ... all done by memory.

I should hope so. I don't think any of my engineering classmates could
have passed for a BS without memorizing more conversion factors than
that.  For acres I just remember that a square mile is 640 acres (a
section).  The canonical acre is 1/8 mile * 1/80 mile.

But OK, I can probably cram in that 98 pounds = 7 stones.

"7 stone", not "7 stones".

(Do they have an actual stone stored away somewhere, like they used to
have an actual kilogram?)

No idea.  Different scales of weight for different items was once
considered natural. Troy ounces and pounds still survive.  12 Troy
ounces per pound, of course.  "Grain" for gunpowder or drugs is also
still in use, although in the case of drugs I think it's mostly just
aspirin labels.
