When the original value is only precise to plus or minus half an inch, it makes no sense whatsoever to do a conversion that’s a hundred times more precise.
A man says he’s 6’6". Sure. If he’s anywhere between 6’5½" and 6’6½", that’s true.
You say he’s 198.12cm tall. The range of this being true is now thinner than a needle. It has gone far beyond what anyone actually measures. In over 99% of cases, it’s not true, and if it is, it won’t be for long, because the human body isn’t nearly that consistent from breath to breath.
The conversion with spurious false precision has made the number go from true to not true.
The man is six foot six, yes, true.
The man is 198.12cm - no he isn’t.

It’s more precise and took no extra effort. 🤷
Why is it bothering you so much?
It’s not more precise, it becomes inaccurate.

This is exactly right. 👏🏼
It really doesn’t though.
