Significant Figures The Significant Figures of a number refer to those digits that have meaning in reference to a measured or specified value. Correctly accounting for Significant Figures is important while performing arithmetic so that the resulting answers accurately represent numbers that have computational significance or value.

Significant digits or figures are not something we make up to terrorize you all semester long. They represent the accuracy of a measurement. For example, a cheap bathroom scale bought at the dollar store reads your weight as 152 pounds, not 152.45809 pounds. It is not that accurate. Significant digits are very important in all measurements.

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

There are three rules on determining how many significant figures are in a number: 1. Non-zero digits are always significant. 2. Any zeros between two significant digits are significant. 3. A final zero or trailing zeros in the decimal portion ONLY are significant. Focus on these rules and learn them well. They will be used extensively ...

(1) All nonzero digits are significant: 1.234 g has 4 significant figures, 1.2 g has 2 significant figures. (2) Zeroes between nonzero digits are significant: 1002 kg has 4 significant figures, 3.07 mL has 3 significant figures. (3) Zeroes to the left of the first nonzero digits are not significant; such zeroes merely indicate the
