I just find it ridiculous that the US of the entire world is unable to get away with it, the system is very bad when you apply some basic elementary education into it.
The debate of which is easier to use comes from the sense of comfort because you are used to it, it’s also weird because from the moment we are children we are taught math in the forms of 10s so understanding the Metric system should be so basic, far more basic than memorizing Imperialist measurements.
I can also go on Farenheit and how dates are ordered for how confusing it is but that would take a while.
Also unpopular opinion YYYY/MM/DD is very good set up than DD/MM/YYYY.
