Your examples with even numbers in feet and odd in meters tell me that is what you’re used to.
I can counter with that saying 180 cm is a lot easier than 5 feet 10.86 inches. No one says that, similar to that no one would say 17.78.
What’s convenient with metric is that there isn’t any difference between saying 180 or 179 cm. You just say, “one seventy nine”, not “one hundred and seventy nine”. Here I am showing what I am used to.
