All non-zero numbers ARE significant (3492 has 4 sig figs). Any zeros that are between non-zeros are also considered significant (3,400,008 has 7 sig figs). Any zeros that follow immediately to the right of the decimal place in numbers smaller than one ARE NOT considered significant (0.000000348 has 3 sig figs).

The number 13.20 is said to have 4 significant figures. Rules for deciding the number of significant figures in a measured quantity: (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 ...

These rules are: 1. Significant numbers are always measurements and thus should always be accompanied by the . measurement's unit. For simplicity, units are not included in the following examples. 2. Any numbers (that are measurements) other than zero are significant. (Many times the zeros are also . significant as you will see below.) Thus . 123.45. contains five significant digits. 3. …
