Significant Figures - Purdue University
Significant Figures The number of significant figures is the number of digits whose values are known with certainty. The numerical values of the experimental results must be written according to specific rules. The number of significant figures that should be used in stating a result is inseparably

The rules for significant figures can be summarized as follows: 1. To determine the number of significant figures: o All nonzero digits are significant. (1.234 has 4 sig figs) o Zeroes between nonzero digits are significant. (1.02 has 3 sig figs) o Zeroes to the left of the first nonzero digits are not significant. (0.012 has 2

of the digits have meaning (significance) and, therefore, should not be written down. In science, only the numbers that have significance (derived from measurement) are written. If you're not convinced significant figures are important, you may want to read the Significant Figure Fable that follows. Rule 1: Non-zero digits are always significant.
