    Does anyone happen to know the calibration uncertainty of a protractor or a travelling microscope?


    :confused:


    Or know of any good sites that lists these things?

    Thanks

    officially the uncertainty due to reading an instrument is equal to the smallest scale division on it. A standard protractor has lines at 1/2 degree intervals so your uncertainty is +/- 0.5 degrees
