The parent comment you are replying to is making a statement about precision vs other metrics such as user familiarity, accuracy, etc. The size of an American Penny and a 9v battery are both very precise, the former even more so. The lack of universitality is a different argument, the tangent your comment discusses.
"Precise" has a precise meaning, and it was a pedantic (though in a way I appreciate) comment on that. Your lack of familiarity with "American" pennies does not change that they are a very well defined size.
This often comes up in science discussions because to many lay people "Precise", "Accurate" and other terms are used interchangeably, when they have distinct meanings
