Do the Europeans make more sense when it comes to floor counting?
Floor 1 is also sometimes called the Ground Floor. (The floor above is 2 and so on.) On many elevators they use G instead of a 1. Below the Ground Floor is the Basement. If there is more than one level below ground, they'll be called a different name which ordinarily describes their function, such as Storage Room, Boiler Room, Utility Room, Morgue, Laundry Room, etc. Mathematically, a Negative describes what does not exist. Apply this concept to a building and it's pretty bizarre. -1 Floor would be the floor which does not exist below the Ground Floor. -2 Floor would be the floor that doesn't exist two stories below the ground floor. Working on this logic, all buildings which do not use the basement-naming method, would have an infinite number of negative floors beneath them, that is, if the floors continued through the Earth's core and on out into space. Therefore, the use of Floor Zero is nominal, and could never be a mathematical construct, any more than the wor Ground Level can be a mathematical construct. My building (US) calls the street level floor Ground Level only, and it's never called the First Floor. The 1st Floor is therefore 2 stories above the street, and so on. If it were possible to think of the Basement as -1 Floor, which of course you can't because to think of it in this way would automatically cause it to not exist, but IF.......In the case of my building, the Basement (-1 Floor) actually IS 2 floors distant from the First Floor. MANY buildings within old cities have this naming style. Niiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii... question and fun!
