Reading a ruler in CM is straightforward. Locate the '0' mark on the ruler and align it with the starting point of what you're measuring. Each numbered marking represents a full centimeter. The smaller lines between the numbers denote millimeters; each full centimeter has 10 millimeter divisions. For precise measurements, count the significant marks. For example, if an object's edge is at the 5th small line past '4', it measures 4.5 cm.
