Teslas do this, they show battery charge in terms of miles or kilometers which is obviously not the correct unit. It's more abstract and often wrong but closer to what the person wants to know.
Oddly enough the iPhone doesn't do this, it will happily tell you how many GB you have left when what the user really wants to know is "How many more songs or photos can I store?".
