I grew up when metric was replacing "imperial" in Canada. The road signs had mph and kph, thermometers all have C and F, tape measures have both (lumber is still sold as a 2x4, its pre-finished dimension). Socket sets. God. Anyway, metric just makes sense for most things. The attachment is cultural. My parents talked about my height and weight in the old units. I still use them and so do government forms. But there's nothing "good" about the old stuff. It's just what you are used to.
