But there is! Firstly, if you cut a piece of A4 paper into two halves,
each has the same proportions as A4. Secondly, a piece of An paper has
area 1/2**n of a square metre. Standard photocopier paper weighs 80
grams a square metre, so a piece of A4 weights 5 g, and airmail
postage rates go in steps of 5 g or 10 g ...

Of course, it's not really 210x297mm; it's more like 210.224x297.302mm.
