Inches and centimeters are both units used to measure length. Keep reading to learn more about each unit of measure.
Inches
An inch is a unit of linear length measure equal to 1/12 of a foot or 1/36 of a yard. Because the international yard is legally defined to be equal to exactly 0.9144 meters, one inch is equal to 2.54 centimeters.<1>
The inch is a US customary and imperial unit of length. Inches can be abbreviated as in; for example, 1 inch can be written as 1 in.
Inches can also be denoted using the ″ symbol, otherwise known as a double-prime. Often a double-quote (“) is used instead of a double-prime for convenience. A double-prime is commonly used to express 1 in as 1″.

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.
We recommend using a ruler or tape measure for measuring length, which can be found at a local retailer or home center. Rulers are available in imperial, metric, or combination with both values, so make sure you get the correct type for your needs.
