According to the poll, Metric is more popular by a landslide. Even among American members.
I still don't really like the metric system. I may have to get used to it when I'm in science, but I'm not going to adapt to it being our primary system for anything other than science.
However, unlike most arguments, there isn't a strong argument that defends the imperial system, yet I don't believe in forcing people to change their lifestyles.
