# Centimeter vs. Millimeter: What's the Difference?

Edited by Sara Rehman || By Sawaira Riaz || Published on December 5, 2023
A centimeter is a unit of length in the metric system equal to one hundredth of a meter, while a millimeter is one thousandth of a meter.

## Key Differences

A centimeter (cm) is a unit of length in the metric system, often used to measure small distances. In contrast, a millimeter (mm) is a smaller metric unit, used for even finer measurements.
