Centimeter Definition and Usage
One centimeter is equal to one-hundredth (1/100) of a meter, which is defined as the distance light travels in a vacuum in a 1/299,792,458 second time interval.
The centimeter, or centimetre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "centi" is the prefix for 10-2. Centimeters can be abbreviated as cm; for example, 1 centimeter can be written as 1 cm.
Metric rulers typically have 30 cm, which are represented by 30 large tick marks. To get a rough idea of the actual length of a centimeter, a standard pencil is just about 1 cm thick.
