Significant figures, or digits, are the values in a number that can be counted on to be accurate. Significant digits in a number are those values which can be known with certainty or a high degree of confidence, while insignificant digits are those which we do not trust as very accurate.

The number may be rounded or padded with zeros to give it the correct number of significant figures. When multiplying values together, your result is only as significant as your least significant value.

The first digit dropped is 1, so we do not round up. Scientific notation provides a way of communicating significant figures without ambiguity. You simply include all the significant figures in the leading number. The first significant digit is 4 because it is the first digit that is not zero.

Significant figures are used to ensure that a measurement is honest and accurate. For example, a ruler with marks on each inch, but nothing more, would not be accurate enough to determine half inches or quarter inches. In this case, measurements made by that ruler would have only one significant figure (1 inch or 6 inches, as opposed to 1.5 or 6.2 inches, which contain two significant figures). Rules for counting significant figures are summarized below. Zeros within a number are always significant.
