A standard rule of thumb is to report the standard uncertainty with at most two significant digits. By example. ± 1.245 → ± 1.2. ± 0.01245 → ± 0.012. ± 1245. → ± 1.2 × 10 3. The next step is to round the average value according to the significant digits in the uncertainty. By example.

For example, a ruler with marks on each inch, but nothing more, would not be accurate enough to determine half inches or quarter inches. In this case, measurements made by that ruler would have only one significant figure (1 inch or 6 inches, as opposed …
