sorry but i learned both as a child so to be awkward i use the most convenient at the time-useually feet/yards for long things, inches for shorter things, then go to millimetres for really small things-sounds wierd but easiest for me personally!

The stick is about an inch and a half thich and intend to bore a hole just under an inch thick in the top.

The stick is about 6foot high but i intend to use about 4-5foot of that(personal preference)
