I design elevators all over the world
There is soft metric (like 163mm), hard metric (would be rounded to 165mm) imperial like 1-1/16" and then some places/clients do not work in anything under 1/4" so everything gets rounded.....its a real PITA
Hard metric should have been the way the world works!!!
It makes the most sense and is easiest to work with.......no fractions to deal with and everything can fit inside of everything else without having to round numbers!!
this is just the math we are talking about then you have elevator codes to deal with and the different municipalities that interpret those codes....the great state of CA has its own elevator code (of course). Anyplace that was colonized by the British follows the EN81 elevator code but then they have been adopting western ideas into their code for quite a few years which all comes down to the guy who is reading the code and his interpretation.....basically your standard passenger elevator varies a huge amount depending on who what when and why its being installed. Asians do not mind cramming into each other to fit more people into a car, Americans would not hear of touching shoulders for the most part so car loads vary widely....there is alot to know! I call it job security, this is why the world needs "consultants" we do not sell products or ideas we sell information and knowledge. I just wish somebody would have told me I could make $18 million a year playing left field for some baseball team...life would have been much more simple :) Catch the ball, run back to dug out...collect paycheck.
