This sig fig counter counts the significant digits or simply rounds a digit to the desired number of a significant figure. Significant figs are the number of digits that are used to express a measured or calculated quantity. Remember, trailing zeros in the decimals place still contribute meaning as Numbers can be rounded to a given number of significant figures, for example when the measurement device cannot produce accurate results to a given resolution. If any result or rounded result under Rule 2 has 1 as the main significant digit and none of the operands has 1 as the leading significant digit, keep the additional significant digit in the result until you are sure that the leading digit remains. Read more below for doing math with significant figures. 100.00 has five significant figures. To avoid rounding error during multistage calculations, keep an additional significant figure for the mean scores. e.g., in terms of significant figures, in a pH calculation where the [H 3 O +] = 2.22 x 10 -3 M. (0.012 has 2 sig figs) If you want to measure 100 with 3 sig figures (implying uncertainty of), then you could write it as 100.. They allow scientists to measure uncertainty and make better decisions. (27.2 x 15.63) 1.846 = 230.3011918 (this is what you calculator spits out) In this case, since your final answer it limited to three sig figs, the answer is 230.
