What’s crazy is that it’s not consistent by language. Obviously we have British/Aussie/Kiwi vs US/Canadian English, but the Spanish speaking world is also fractured.
And not even by otherwise closely related geographical regions. The Nordics, one of the world’s most internally cooperative group of countries, have Sweden and Denmark using the English British system, and Finland and Norway using the British American system.
Edit: I’m a dumbass
Did you mean to say American for one of those systems? England is part of Great Britain.
Antarctica is mixed… that means there are at least two multifloor buildings there… and they couldn’t agree on it
What? Why? On the east coast I’ve mostly seen ground as first floor. Sometimes below ground is counted though.
I’ve worked on a few buildings in Quebec that all use the European style. hate it!
