Contrary to what this article claims,  I would say that the motivation for such a switch has never been weaker.<p>- The switch to metric has already taken place in science and engineering (where it&#x27;s most harmful to have 2 systems), largely because of the horror stories from decades past mentioned in the article.<p>- Packaging and labeling costs associated with having 2 systems is effectively zero because it&#x27;s all automated.<p>- 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)<p>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.<p>TLDR; The metric crusaders need to find a new cause to pour their energies into.
