As someone who grew up with metric measurements, I could easily use the exact same "practicality" arguments against the imperial system. To me, an inch is a weird measurement that is slightly longer than 2cm, a mile is a bit farther than 1.5km, a gallon is about 4 litres, and I always have to lookup up what ounces are (let alone fluid ounces -- which I have to constantly remind myself are not the same thing). But that isn't because the imperial system is "less practical" in any meaningful sense -- it's just that I didn't grow up with it and so I have to constantly convert back to the system I know (and since the conversions will never be nice integer ratios, of course your "native" measuring system will appear to work better). As for the whole "imperial fractions are easier to deal with" thing, I personally disagree but I suspect that's also because I'm not used to the idea. In everyday life I'm so used to seeing decimal quantities that from a young age I learned how to quickly deal with them. However, I must admit I struggle to handle fractions as quickly because it isn't as common as decimal division in my everyday life. I imagine the inverse is probably true for people who have dealt with fractional quantities their entire lives. I hasten to point out that most people wouldn't say nor think of 1.5cm as "1 centimetre and 5 millimetres", just as you wouldn't say nor think of 1⅝ inches as "1 inch and 5 eighths-of-an-inch". Honestly this whole argument has always felt pointless to me -- is it not obvious that you will always find things you are most familiar to be the best tools for the job? It's almost like watching an Englishman and a Frenchman hotly debating which language is uniquely better suited to writing poetry -- all the while ignoring that equally brilliant poetry has been written in both languages.
