Wait for the old spanish way of doing it. It was abandoned some 40-50 years ago and now we use the same as the british system, but the traditional way of doing it was (bottom to top on this same image):
-Bajos
-Entresuelo
-Principal
-First
More or less everybody except US and Russia has zero floor, counting in big office buildings is fun: 3,2,1,-1,-2, I know... The concept of a number zero is not that old (couple hundred years, don't remember the details), but should be enough to update your language :-*
I did a quick search, it seems it's similar to imperial and metric in that it's only the US doing 1st floor as ground floor. It's for various reasons, but in most European languages the word used for the numbered "floors" either means "horizontal division between floors" or the first "construction over the previous floor", so it makes sense that the first is the first above the ground.
It's like the basement, the ground floor is special.
As someone who does a bit of programming, I think a 256 story tall building should have floors 0-255. But as an American there should be 257 total floors so we can skip floor 13 because it's bad luck.
I've worked in two U.S. buildings with Both ground and first floors. The buildings were built into a hill so street level entered the first floor, but parking entered the ground floor. Very easy to get confused until you figure it out.
Seems like Brazil adopted the British system, at least the buildings I went: here, the immediate floor is called "Térreo" (Ground), followed by "primeiro andar" ("First floor") and so on.
In German we call the floors "Geschoss" we have "Erdgeschoss" (earth-floor) and then "Obergeschoss" (above-floor) "Untergeschoss" (under-floor). So you have the ground floor called EG, above it is 1.OG then 2.OG, etc. From the EG downwards there is the 1.UG and further down the 2.UG, etc.
With this terminology there can't be any confusion, because there needs to be a reference floor from which to count up and down. Lucky us.
I learned this when I was a wee lad: I was playing Runescape and trying to solve a quest I was stuck on with a walkthrough. The guide said that the macguffin was on the first floor of some building, and I must have spent hours looking on the ground floor with no luck.
I finally asked my big brother for help and he said, "Have you tried looking upstairs?"
And there it was, blew my mind.
Never understood how ground floor and first floor aren't always synonymous. If the ground floor is a floor, then how could it not be the first of the floors?
In the US we use either 1st floor and Ground floor to refer to the same floor. The second and higher floors are consistently named though, except for those buildings that skip the 13th floor.
This is surprisingly annoying where I live and some houses use the British way and everyone uses the American way in speech.
We live on the American second floor. So whenever someone new comes to visit there is no easy answer to where our apartment is: if I tell them we are on the first floor, they won’t find us looking on the ground floor. If I say come to the second floor, they may use the elevator and press 2 which will then take them to the third floor.
Happens almost every time I’m not specific enough.
In Europe a lot of countries name the "ground level" floor something because historically "zero" was a bad number, so they instead called it something else because the logic was to start at 0.
It's kinda like how some buildings in the USA exclude the 13th floor.
Little fun fact btw - the whole foods database used to exclude Friday the 13th. Found this out when I worked there and was trying to show my receipt for something I got, and when the manager looked, we couldn't find it. Then another coworker came in and brought up something they brought up the day before and it couldn't be found either.
After a bit, we found it Thursday 12th, but then when scrolling saw it skipped Friday 13th and instead went straight to Saturday 14th.
The benefit of starting the number at 1 is the majority of apartment blocks and hotels can have 4 digit room numbers with the first digit representing the floor it's on.
E.g. room 4201 is on 4th floor and 1691 is on 1st floor
The older buildings in Hong Kong often need to clarify this to avoid mix ups. Back in the day it's not uncommon to see signs advertising a business on the 3rd floor of a building, for example, to have 3 樓 2字 (3rd floor, number 2) to tell people they're on the 3rd floor but you need the press the 2 button in the lift. Also some (most? all?) skip the 4th floor for bad luck.
Where are the stairs going in that picture? They just make everything more confusing. They seem to go exactly between two levels and not on the bottom level like a normal-ass building.
I wish it was this clear cut in the states. Motherfucking builders treat this like guidelines and I'm never sure what button I need to press to be able to walk outside.
It's definitely not consistent in the states. We use both.
Edit: Oh wait, ground to first? Every time I hear a Brit make fun of the US I have to wonder what crack he's on to lack the self awareness. That's idiotic.
Wait. I am pretty sure that i live in America, and here the buildings start at zero. 012 denotes room 12 on floor zero. Room 112 is the first floor room 12 and so on.
