Significant figures are useful in showing the approximate precision of measurements, but scientists often prefer to state the precision of a measurement exactly. For example, 237.145 ± 0.003 would mean that the measurement could be off by as much as 0.003 up or down, i.e., the real value is somewhere between 237.142 and 237.148.

To measure with significant figures, you count ALL digits. Each one is considered significant. For example, a ruler that reads 1.36 cm has 3 significant figures. A beaker with 12.52 mL of liquid has 4 significant figures. Scientific equipment has markings that let you read its measurement to a certain number of significant figures.

Rules for Writing Significant Figures: 1) All nonzero digits are significant. For example, “3.4 grams” has two significant figures. 2) Zeros that are between nonzero digits are significant. For example, “3.04 grams” has three significant figures. 3) Zeros written to the left of all nonzero digits are not significant

has three significant . digits. The reason that these zeros are not significant is that the measurement . 0.00123 grams. is . equal in magnitude to the measurement . 1.23 milligrams. 1.23. has three significant digits, thus . 0.0123. must also have three significant digits. 7. Any zeros to the right of a number and the right of a decimal point are significant.

12 has two significant figures and 3.00 has three, so the answer should only have two. For example, 3.20 x 5.04 = 16.128 ( 16.1. The starting values only have three significant figures each, so round the answer to three significant figures, 16.1.
