I was wondering if the altitude was the only thing you had to know in order to evaluate the "thinnest of air" at certain point on Earth ? For instance, will climbing a 6000 m peak in the Andes or a 6000 m peak in the Himalayas make any difference in how you need to acclimatize ? (I'm not referring to how tough the climb is.).

I was wondering if the altitude was the only thing you had to know in order to evaluate how dense the oxygen in air is at a certain point on Earth ? For instance, will the oxygen density in air be the same for a 6000 m peak in the Andes and a 6000 m peak in the Himalayas ? Of course, I'm asking wether the oxygen density is roughly the same (and not with infinite precision !).
