Surely that is wrong?

I'll dig out my calipers, I can only test the smaller ones, unless I go to the bank, they might let me play with a C note for awhile. But it can't be a whole lot different than a 1 dollar bill I would think. News at 11.

1 mm is 0.039 and change of an inch. So if it really is 43 thou, it is a bit more than a mm. 1.0922 mm to be exact. Assuming it is 43 thou though.

Well SOMEONE fed us a pile of BS. A CD is 0.045 inch, about 1.1 mm thick. Obviously money is a lot thinner. I found my digital calipers and measured regular printer paper which comes out at 0.004 inch, one tenth of a mm.

We actually had a C note, it turns out to be thinner than a piece of printer paper:

0.003 inch, switched the calipers to mm and it comes out as 0.09 mm.

So 100 bills would be 90 odd cm. Since the accuracy of my calipers is only 2 digits at that thickness, the actual thickness would have to be verified if someone had a stack of 100 bills.... Any volunteers?ðŸ™‚

Only off by a factor of about 10!

So much for google....

Using my own measurements of a 100 dollar bill, it is 2.59 inches wide and a bit over 6 inches long, I had to do a double measurement of that since my caliper is only good to 6 inches, it seems to be about 6.1 inches long. Doing it in mm, 2.59 inches=~65.8 mm, 6.1 inches=~155 mm long. So 65.8X155X0.1=1023.2 mm cubed. The roll at 50 mm wide minus the inner 10 mm=1884mm squaredX65.8mm=123967 mm cubed, dividing the two gives about 121 bills to fit that roll. So we are in agreement and this time with much better size figures. So the grand total comes out to 12100 bucks. Not a bad days work, eh.
