Most standard rulers are 30 centimeters long, which makes 1 centimeter equal to one-thirtieth of the length of a standard 12-inch, or 30-centimeter, ruler. The centimeter is a metric unit of measure that, according to Metric-Conversions, is equal to 0.3937 inches.Know More
The centimeter is a standard unit of measure of length in the metric system, and it is equal to one one-hundredth of a meter. If a meter stick is divided into 100 equal pieces, each one of the pieces is measured as 1 centimeter in length. Inches are a comparable unit of measure of length in the English system. A single inch is equivalent to 2.54 centimeters, so length in inches can be converted to centimeters by multiplying the inches measured by 2.54.
According to Dictionary.com, the word "centimeter" has been in use since the 1800s. It comes from the French word "centum," which means "hundred," and the root of the word is "meter." The standard abbreviation for the word "centimeter" is "cm." Most rulers also show each centimeter sub-divided into 10 smaller, equal portions. These indicate the length of 1 millimeter, which is equal to one one-thousandth of a meter. There are 25.4 millimeters in a single inch.Learn more about Measurements
A person measures in millimeters by comparing the length of the object in question with the tick marks on a metric ruler or the metric side of a standard ruler. The metric side is labeled in millimeters or centimeters with small tick marks that each represent one millimeter.Full Answer >

When measuring the length of a pencil, centimeters are used rather than millimeters because a pencil is more than a centimeter long. Millimeters are used when measuring lengths that are less than a centimeter, such as a pencil's width.Full Answer >
Metric scale rulers commonly use meters, centimeters and millimeters to measure distance, and each measurement is broken down using multiplications of 10. Ten millimeters equal a centimeter and 100 centimeters equal a meter, allowing for simple measurement of distance with no complex mathematical equations required.Full Answer >
