So that your readers know how a number has been rounded, it is important to state the number of significant figures. For example, if you round 475 to 1 significant figure, you can write 475 = 500 (to 1 s.f.). When a number is rounded, the number of significant figures is known as the precision of the number. Start of Example. Example 3

Significant Figures (sig. figs.) are an incredibly useful tool, as if they are used correctly; you can avoid ‘rounding errors’ in multi-stage calculations. For example, if all your working is accurate to 4 sig. figs. then your answer will be correct to 3 sig. figs.

4.6: Significant Figures and Rounding - Chemistry LibreTexts
Rounding 1.2143 to 3 significant figures gives 1.21 . 3. If the first non-significant number to the right is 5 and it is followed by non-zero digits, add 1 to the last digit to be retained and drop all the digits farther to the right. Rounding 1.2256 to 3 sig figs gives 1.23 (round up because the 5 is followed ...

For example: 2.453 becomes 2.5 to two significant figures. 3. When the digit next beyond the one to be retained is exactly five, and the retained digit is even, leave it unchanged; conversely if the digit is odd, increase the retained figure by one (even/odd rounding). Thus, 3.450 becomes 3.4 but 3.550 becomes 3.6 to two significant figures.
