184cm = 6ft
So 6 foot tall (72in) is like a magic number for American men. That's like the threshold for manliness in popular culture. If you were to plot the self-reported heights men in America, you'd absolutely see a dip at 70 and 71 inches, then a big spike at 72in.
What's this magic number in various metric countries? 185cm seems like a sound choice, but I could see it being 190 in some places.
I think there's definitely a threshold around 6' in English cultures, possibly 180 cm in Europe, but in my personal experience it's not seen an important metric as the magic 6' number in Anglo cultures.
Of course it has no bearing on a actual sizes! That’s why the commenter says “manliness in popular culture” and “self-reported heights”. He’s making the point that lots of men who are slightly shorter than 6 feet will lie and say they are 6 feet tall, and wondering if there is a comparable number in cm.
There is no magic number here. The weird emphasis on height is very much an American peculiarity.
Some (maybe most) women don't want to be in a relationship with a guy smaller than them when they wear heels and some like tall guys but that's pretty much it.
I ~think~ that's why someone downvoted you.
To be fair, a cm _is_ less than a foot
As an American, I had to converted the number to mm and the divided it by 25.4 and again by 12. I figured I save somebody else the trouble.
(I upvoted you.)
