Question about Bra' Sizes

[3PcSuit]

My friend in Europe asked me a question about sizes (although I admitted I'm sadly not familiar enough with women's sizes as I'd like to be) and she was asking me about cup sizes varying from brand to brand.
Then I noticed that 36 is way bigger than 80, unless this isn't inches/centimeters? If not, what do the numbers mean?
Thanks.
Hope I posted this in the right place. I got no help in general discussion.

I answered your duplicate question in the General Attire Section early this morning. Have you gone back to see the answer?

No did not see that. Thank you. I posted both of these at the same time, yesterday.
