> In the US, it’s too costly to switch.

What is the estimated cost out of curiosity?

Everything has a cost. NASA estimated their cost was $370 million to switch to metric.

The cost of switching road signs alone was quite expensive. Exit numbers, for example, are often the mile marker number.

Oh yeah, I'm not saying there's zero monetary cost. I'm saying the blocker isn't affordability.
