Metric paper which always has the same ratio of dimensions when folded in half that being 1/sqrt(2). How was the logic behind this derived?
In: Mathematics
US works the same with the 2x scale.
A= 8.5 × 11
B = 11×17
C = 17×22
D = 22×34
E = 34×44
F = 44×68
Those weirdo sizes like legal etc are just derivatives trying to screw up the system.
