Not-super-fun fact: an 8.5 x 11 inch paper can be useful if you lack a ruler in an American office & you need to measure an inch or a foot.
If you fold the paper like in an image I'll try to attach, the hypotenuse is 12.01 inches.
Edit: then you fold the 12.01 inch side against the 11 inch side to get a 1.01 inch measurement
Not exact, but good enough if you need to know your neck size to buy a fancy shirt online - not that I would ever waste my corporation’s time that way!
Not-super-fun fact: you can measure in metric with school notebook paper.
Each sqare is 0.5 by 0.5 cm.
EDIT: 0.5 cm, not mm. For measuring 0.5mm I can use 0.5 mm mechanical pencil lead.
Also there is coordinate paper:
0.1 by 0.1 cm. Or 1 mm grid.
I love how that OP’s solution requires an inexact technique to achieve an even less exact measurement. Like Americans really out here being proud of the stupidest shit
Tiny nitpick: I think you meant 0.5 by 0.5 cm (or 5 by 5 mm).
Also there is coordinate paper:
1 by 1 mm.
Yes, sorry. You are correct
I use it a lot if i need to draw something that is x long. If you do a lot of graphs for example you can use the measurements on your ruler.
Correcting myself: 0.5 cm, not mm.
For graphs you can use graph paper with 1 mm grid.
The motto of the whole imperial unit system.
And most people here know that an A4 is 21 (exactly) by 30 (roughly) cm, which you can use (surprisingly) use for measurement aswell.
21x29.7
This number is permanently stored in my memory, just like 1€ = 6.55957F
I didn’t know Euro and Farad were related :O
Not only that, if you know your A4, you can do all paper sizes in you head: A3 has A4's long side as it's short side, and A4's short side x2 for it's long side. Rinse and repeat.
How does that work? 8.5^2 + 11^2 is 193.25, square root of that is 13.9. Where does 12.01 come from?
Huh. . That’s weird. I could swear I double checked my math before I posted this One Dumb Trick online years and years ago…
Found the mistake, I had skipped a step, updated original post
Oh, that makes a lot more sense now.
Oh no, it's getting worse!
Oh, that's simple and useful.
What a nightmare
