minus-squarelemming741@lemmy.worldlinkfedilinkEnglisharrow-up40·edit-21 年前That’s why I keep a roll of 20 AWG nichrome on hand. Spool off 9.7195853528209 feet and it’ll be bang on.
minus-squareLv_InSaNe_vL@lemmy.worldlinkfedilinkarrow-up5·1 年前So 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-squarelemming741@lemmy.worldlinkfedilinkEnglisharrow-up11·1 年前Yeah which is why you use a Kibble balance. Are you sure you’re cut out for this kind of work?
minus-squareLv_InSaNe_vL@lemmy.worldlinkfedilinkarrow-up3·1 年前I’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!
minus-squarelemming741@lemmy.worldlinkfedilinkEnglisharrow-up3·1 年前Its akin to having an electon microscope in your kitchen
minus-squareOpisek@lemmy.worldlinkfedilinkarrow-up4·edit-21 年前We move onto the next issue. How to precisely measure the length of the wire?
minus-squareZombiFrancis@sh.itjust.workslinkfedilinkarrow-up7·1 年前Eyeball it. Gotta squint right tho.

With a 6 digit voltmeter
With an ohm meter?
