minus-squarelemming741@lemmy.worldlinkfedilinkEnglisharrow-up38·edit-22 个月前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-up5·2 个月前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-squareOpisek@lemmy.worldlinkfedilinkarrow-up4·edit-22 个月前We move onto the next issue. How to precisely measure the length of the wire?
minus-squareZombiFrancis@sh.itjust.workslinkfedilinkarrow-up7·2 个月前Eyeball it. Gotta squint right tho.

With a 6 digit voltmeter
With an ohm meter?
