Nanoraptor in Elk: "iso paper sizes are delicious: sides are..."

iso paper sizes are delicious: sides are 1:sqrt2 or about 1:1.414

A4 is 210x297mm

A4 folded in half is 148x210 or A5.

A3 is two A4s, or 297x420

go to A0 841x1189 or one square metre.

A-1 (A Minus One) is 2 square metres.

Australia is ~A-43

The visible universe ~A-179

A proton about A139.

A Quark? A151

Presumably A232 is one dimensional though, as it's planck length on the long edge.

> iso paper sizes are delicious

In contrast, US paper sizes are like licking a 9v battery

could not agree. Licking 9v could be a little entertaining. US formats are only pain .

can't keep the ratio with these physics, geez...

Now to calculate the negative A-number for a universe-wrapping sheet.

and the B paper sizes are the geometric mean in-between A sizes!

Hmm... it should be surprisingly easy to calculate the weight of the entire visible universe using an A0 sheet then…

Today's universe is 90gsm

A-179 printer jams are a bitch.
