Contrary to what this article claims, I would say that the motivation for such a switch has never been weaker. - The switch to metric has already taken place in science and engineering (where it's most harmful to have 2 systems), largely because of the horror stories from decades past mentioned in the article. - Packaging and labeling costs associated with having 2 systems is effectively zero because it's all automated. - Everyone has a computer in their pocket capable of performing a conversion if they really get in a bind (though this has literally never happened to me) On the other hand, people are generally content with using the imperial system so a switch would be met with a lot of resistance. This resistance, coupled with increasingly vanishing costs associated with having 2 systems leads me to believe that this switch is not going to happen in my lifetime. TLDR; The metric crusaders need to find a new cause to pour their energies into.
