The measurements are decimalized and there are no fractions. Line up your metric ruler against the object you wish to measure, with one end of the object aligned with the 0 point of the ruler. Count the number of centimeter lines from the beginning of the object to the end.
For example, your object may be 9 cm long. Count the number of millimeter lines, if necessary.
For example, your object may extend 8 millimeter lines beyond the 9 mark. Your object would then measure 9. You can convert centimeter measurements into millimeter measurements by multiplying the number by For example, an object that is 9.
Stack of centimeter rules more per page, but shorter 20 cm long, 2 cm wide. Dense stack of centimeter rules lots more per pagebut shorter and narrower 20 cm long, 1. Dense stack of centimeter rules more, but narrower 25 cm long, 1.
