The American way is still thinking of a floor as the thing you stand on. We call the first floor that you step on in the building the “first floor” and going up we call the second floor you stand on the “second floor”. Going down to the basement, we call it B1 because its the first floor you step on in the basement amd so on going down.
Europeans call the first floor that you step on the “ground floor” and the second floor that you stand on the “first floor”. Going down, the first floor you hit underground is called "-1 and so on, very similarly to the American system. The naming of floors aboveground doesn’t make logical sense to me, as they should be named for ease of navigation. ~~Telling someone that they need to go up 3 floors and then turn left on the 2nd floor hallway is inherently confusing. ~~
Edit: sorry got that example mixed up.
If you’re building a house I’m Europe and the ask how many floors to build and you say “2”. Are they going to build the floor that sits on the ground and one more or are they going to build the floor that sits on the ground and two more? The naming system lends itself to confusion.
I’m an American that lives in Italy about half of the time. I was being facetious a bit, but it is true that there is a cultural differences in how people think about this, it’s not just words. Someone else commented on the German words for it, which (as is typical with German over Romantic languages) is more appropriately descriptive.
“Go up 3 floors and turn left.” in the US would put you on the fourth floor, but in Europe each floor you go up is the number of the floor you are on. It’s more common in the US to say “Go up to the 2nd floor.” unless you’re not starting on the 1st floor.
In Europe if you say “I want a building with 7 floors.” no one will be confused, they will know that you want a ground floor and 7 above ground floors. They would probably also know what an American means when they say it. Only the Americans would be confused and they hilariously are as they look for their AirBnB’s here on vacation!
