What Is a Centimeter?

A cen­time­ter (cm) is a unit of length in the met­ric sys­tem, which is wide­ly used world­wide (except in a few coun­tries like the Unit­ed States, where the impe­r­i­al sys­tem dom­i­nates).

Quick facts about centimeters:

• It is part of the Inter­na­tion­al Sys­tem of Units (SI).
• “Cen­ti” means one-hun­dredth, so a cen­time­ter is 1/100th of a meter.
• Cen­time­ters are com­mon­ly used for small­er mea­sure­ments like the length of a pen or the width of a phone.

For exam­ple:

• The width of an aver­age note­book is approx­i­mate­ly 20 cen­time­ters.

More about the met­ric sys­tem can be found on The Inter­na­tion­al Sys­tem of Units web­site.

What Is an Inch?

An inch (in) is a unit of length in the impe­r­i­al sys­tem, large­ly used in the Unit­ed States, Cana­da, and the Unit­ed King­dom for mea­sure­ment.

Quick facts about inches:

• It is part of the stan­dard impe­r­i­al sys­tem.
• His­tor­i­cal­ly, an inch was defined by the width of a man’s thumb or three grains of bar­ley.
• One yard equals 36 inch­es.

For exam­ple:

• The width of an aver­age smart­phone is about 3 inch­es.
