Understanding the Centimeter
Before we look at examples, it helps to understand what a centimeter actually is.
A centimeter is part of the metric system, which is used in most countries around the world. It is a common unit for measuring small objects and short distances. In the metric system:
- 10 millimeters = 1 centimeter
- 100 centimeters = 1 meter
Since 2 cm equals 20 millimeters, it is often used when measuring small objects such as jewelry, buttons, screws, or small craft materials.
Because the metric system is simple and easy to scale, centimeters are commonly used in schools, science, construction, and product design.
