You can buy these with a calibration certificate for like $70, but I skipped the cert. Should be the same quality, cost me $16. I chose the version with the superior units of measurement.
If it’s the same loosy-goosy metal catch that’s sort of dangles on a rivet, you’re always going to be 2-3 mm wrong regardless of the precision of the tape itself.
Edit: I now know that didnt know how to use a measuring tape and I feel enlightened, relieved and somewhat embarrassed - thanks all for helping learn something new.
