The centimeter is commonly used for everyday measurements when precision to the nearest millimeter is not necessary. It is a convenient unit for measuring the dimensions of objects such as furniture, clothing, and body measurements. The symbol for centimeter is “cm”.

## What is an Inch?

An inch (symbol: in) is a unit of length in the imperial and US customary systems of measurement. Historically, an inch was defined as the width of a man’s thumb, but it has since been standardized to an exact measurement. One inch is defined as exactly 25.4 millimeters or 2.54 centimeters.

**Here are some key facts about inches:**
