I had no idea about the floors and decimals! And I've been to Europe, albeit briefly (you think I would've found out there...)

I think they used metrics because the US is literally the ONLY country in the world that doesn't use it (why we haven't switched I have no idea... People say it's because its too expensive, but if all the other countries have switched in my opinion it's too expensive NOT to...).
