    meter stick = o.1cm vernier = 0.01 cm micrometer = 0.001cm relative uncertainity for 2cm will be for meter stick = (0.1/2 )*100% = 5% vernier = (0.01/2)*100% = 0.5% micrometer = (0.001/ 2)*100% = 0.05%

    no i had already worked the precisions in cm

    another person told me if you measure it to be 2cm with any of the above instruments then the measurement will look like this 2cm±precision or 2cm±uncertainty so report plus or minus your precision as your uncertainty.

    so 4 meter stick= 2cm± 0.05 vernier = 2cm± 0.005 miocrometer= 2cm± 0.0005 this means that measurements using a micrometer are more precise and accurate

    what i had given before was the % precisions using the various instruments.
