I only happebn to know 13mm-1/2" and 19mm-3/4. No more bytes left in memory.
I wrote the size (all are metric now) of EACH oil drain plug on the painted surface near the radiator under the hood of the cars (and truck)
I can not even come close to guessing in metric,, and I sure do not want to climb under the car an extra time,,
I am thinking about writing the oil change date there,, also,, I now keep a magic marker in the socket drawer,, just to do this .
