Floor wiki:
[ecture">architecture, a floor is generally the lower horizontal surface of a room (see also flooring). The various levels of rooms in a building are also called floors or stories (storeys in British English): "ground floor", "first story", "mezzanine floor", etc. A confusion arises between the two forms of floor numbering in use worldwide. In most of Europe, and thus British usage, the floor at the ground level is the ground floor, and the floor above is the first floor, which maintains the continental European use dating from the days of the construction of palaces. For example, in French, the term for the ground floor is rez de chaussée. But in North American usage (except in Quebec), the floor at the ground level is usually, but not always, the first floor and the floor above is the second floor; this system is also used in Russia and other countries of the former Soviet Union.
