The US already uses the metric system. It is taught to every child in school. Engineers and scientists use it as their default.

What the soi-disant pro-metric faction really wants is to stamp out the English system from the culture. Why can't they tolerate people measuring themselves, their recipes, their temperatures, and their vehicle speeds in their preferred units?

Actually, is more a Roman system than English.

I think there has already been significant discussion here about what the advantages (and disadvantages) are.

The US rarely uses metric in it's popular culture. Weather reports are in Fahrenheit, movies almost always use miles and pounds. By any measure of cultural output that you export that I've seen (and Australia is a huge consumer of your popular culture) you do not use metric.

I've heard the argument that the US already uses the metric system before by people who are resistant to the US using the metric system. It always sounds disingenuous.

But I may be wrong. I have not walked one point six one kilometres in your shoes.
