IEEE Std 260.1 suggests using "m2" instead of "sq m" when superscripts
are not available. One could also use "m^2".

A0 = 1 square meter (but it's not a square). If paper is 80g/sq m (sorry
for no superscript, it's late), then it weights 80 g.
A1 = half a square meter = 40 g
A2 = quarter square meter = 20 g
A3 = eighth square meter = 10 g
A4 = sixteenth square meter = 5 g
So if your country ups the postage after 30 g you know you can put five
pieces of paper into a 5 g envelope and pay only basic postage.

But we also know that the "A" series is no more SI-based than my
Great-Aunt Penelope's petunia patch. So, this is indeed an off-topic

An A0 sheet is one square meter (minus 51 mm², which is easy to add back by
changing the temperature and humidity). A B0 sheet is 1 m on a side.
