The world would be better off to completely convert to metric, especially since industrialization, and all means of modern connection and communication is making the fabric of humanity so interwoven. Except for mechanics, it would be relatively easy to convert.
Converting to metric nuts and bolts is coming, but what about thread sizes? Even metric bolt heads still have TPI threads......
Mechanical things will eventually convert, but it's going to take a long time.
How about language? At present, English is the standard for international communication, but will it be the standard for all time? How will the world convert to an international language? As well, the world would be better off to convert to an international language, but that's a really tough end game to consider.
How about time? would we be better off with days divided by 100 increments instead of 24 hours? What would "noon" and "midnight" become?
There will never be a change in the number of days per year, because it's based on a physical reality......just like distance measurements are for metric.
Celsius instead of Fahrenheit is something that can't be converted soon enough......
