      Significant Figures (Sig. Figs.) The mass of an object weighed on a triple beam balance (precision ± 0.1g) is found to be 23.6 g. This quantity contains 3 significant figures, i.e., three experimentally meaningful digits. If the same measurement is made with an analytical balance (precision ± 0.0001g) , the mass might be 23.5820 g (6 sig. fig.)

      Two "rules of thumb" help determine how many significant figures to record in a calculated result. (1) In multiplication or division the result should not contain more significant figures than the measurement with the fewest number of significant digits, e.g., 12.3/3.2 (3 and 2 significant figures respectively) = 3.8 (2 significant figures).
