Why use significant figures? Click on the graphic to read a story that shows the importance of understanding significant figures.

Significant Figures Note: A significant figure is any digit of a number that is known with certainty.

Measuring with Significant Figures Note: When making a measurement in lab, the last digit is always an estimate. Example 1: The volume of the liquid in the graduated cylinder is ________ mL Example 2: The object has a length of _________ cm.
