What is Millimeters to Centimeters Conversion?
Millimeters (mm) and centimeters (cm) are both units of length in the metric system, which is used all over the world. Think of it like this: millimeters are very small, like the thickness of a dime, while centimeters are a bit bigger, about the width of your pinky fingernail.
This converter helps you easily change measurements from millimeters to centimeters, and vice-versa.
Millimeter to Centimeter Formula
Centimeters = Millimeters ÷ 10
Example: 20 mm ÷ 10 = 2 cm. So, 20 millimeters is the same as 2 centimeters.
Another Example: If a small screw is 5mm long, it's 5 ÷ 10 = 0.5 cm long.
The key is that there are 10 millimeters in every centimeter. This means 1 millimeter is equal to 0.1 centimeters.
How to Convert (and Why 10 is Important!)
Converting between mm and cm is super easy because of the metric system. Everything is based on the number 10!
