The biggest source of communication issues around these unit systems is that in metric, you're supposed to reach for decimals when working with the units, and in imperial, you're supposed to reach for fractions when working with the units. Which is why the imperial lovers all cry out about their fractions not "working" in metric. Yes, exactly, that is the point. They don't understand that they're reaching for a tool they shouldn't be reaching for, and then they blame the unit system for it.
