I use both... I like using milimeters alot aswell as inches and whatnot. I've never really used the imperial yard I use meters.. And I rarely use centimeters I use inches. I'm a mixed bag in this department.

I honestly think that, while the metric system makes sense and is good for quick calculations, the imperial system is better when planning buildings or other constructions.

I'm American. Metric and its base 10 system will make your mind weak.
