At the same time, from reference point of view, imperial units have two major issues:
1) they are completely arbitrary, defined out of nowhere
2) they are defined differently at different times and places - there's a whole lot of "miles", "ounces" etc
The latter was a terrible mess even in the UK alone where each industry was using a different standard of ounce and there were like 20 of them, and that status quo was maintained primarily in order to screw confused customers 😂
