A0 ≈ 1 m² was new to me but makes perfect sense. Imagine a world where the makers of USB used a similarly elegant naming convention.

- happymellon 4y agoA1 should be ≈1m for it to be elegant.
- dtx1 4y agoA0 = 0 folds of 1m². A1 = 1 fold, ... Though maybe we could have A3.1 Gen 2x2 for thick blue paper with glossy texture folded 4 times but 2 of those folds weren't down the middle.
- happymellon 4y agoOh I completely get that 0 = 0 folds, but if we are comparing square meters then A1 is 1 square meter. It depends on your point of view on what you are comparing.
- ajuc 4y agoA0 area = 0.5^0 = 1 m^2 A1 area = 0.5^1 = 0.5 m^2 A2 area = 0.5^2 = 0.25 m^2 A3 area = 0.5^3 = 0.125 m^2 If it was your way A1 area = 1 m^2 A2 area = 0.5 = 0.5 ^ (2-1) m^2 A3 area = 0.25 = 0.5 ^ (3-1) m^2 Why shift it one way just to shift it the other way in the formula?
- Infernal 4y agoIf you want to fit the area into the name you can think of it as A0 = 1/(2^0) m^2 A1 = 1/(2^1) m^2 A2 = 1/(2^2) m^2 And so on (EDIT for formatting and also to observe a sibling post to mine is making the same point)
- Symbiote 4y agoNo, because 2⁰ = 1. Paper weight is measure in grammes per square metre. 80gsm is typical for ordinary paper. A0 = 2⁰ m² = 1 m² → 80g A1 = 2¯¹ m² = 0.5 m² → 40g ... A4 = 2¯⁴ m² = 0.0625 m² → 5g (Fixed typo, thanks.)
- demurgos 4y agoSmall nit: A1 should be half the mass of A0 (40g in your example).
