A Short Guide to Signiﬁcant Figures What is a “signiﬁcant ﬁgure”? The number of signiﬁcant ﬁgures in a result is simply the number of ﬁgures that are known with some degree of reliability. The number 13.2 is said to have 3 signiﬁcant ﬁgures. The number 13.20 is said to have 4 signiﬁcant ﬁgures.

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

Are Significant Figures Important? A Fable A student once needed a cube of metal that had to have a mass of 83 grams. He knew the density of this metal was 8.67 g/mL, which told him the cube's volume. Believing significant figures were invented just to make life difficult for chemistry students and had no practical use in the

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.

Chapter 3 – Significant Figures Overview “Significant figures” is a term that refers to the number of digits in an experimentially derived number that give useful information about the data quality. Data with many significant figures is considered to be precise, and usually implies greater accuracy.
