minus-square@[email protected]linkfedilink4•edit-220 days agoWe move onto the next issue. How to precisely measure the length of the wire?
minus-square@[email protected]linkfedilinkEnglish6•20 days agoIf you trust the gauging, you weigh it.
minus-squareLv_InSaNe_vLlinkfedilink5•20 days agoSo 1 inch of your wire would weigh ~0.0987 grams, so to measure down to 8.6350242338508 inches of wire your scale would need to weigh down to ~0.00000000000007 grams. Which is the weight of about a dozen atoms or so.
minus-square@[email protected]linkfedilinkEnglish10•20 days agoYeah which is why you use a Kibble balance. Are you sure you’re cut out for this kind of work?
minus-squareLv_InSaNe_vLlinkfedilink3•20 days agoI’m not a scientist, I’m just in IT haha I figured there was a way to measure that small of weight but I didn’t know!

With an ohm meter?

Eyeball it. Gotta squint right tho.
With a 6 digit voltmeter
