First of all, please note that ‘cm’ is the same as ‘centimeters’ and ‘nm’ is the same as ‘nanometers’. Both, Centimeters and nanometers are units, used to measure length. Thus, when you are asking to convert cm to nm, you are asking to convert 1 centimeters to nanometers.

A centimeter is larger than a nanometer. In fact, a centimeter is ’10 to the power of 7′ larger than a nanometer. Since a centimeter is 10^7 larger than a nanometer, it means that the conversion factor for cm to nm is 10^7. Therefore, you can multiply 1 nm by 10^7 to get 1 cm converted to nm.

## How To Convert Centimeters To Nanometers ?

To convert centimeters to nanometers you simply multiply your centimeters by 10000000. The formula would look like this:

[cm = nm * 10000000]

The length in nanometers is equal to the centimeters multiplied by 10,000,000.

Let’s take an example to understand properly:

**Example** – How to convert 5 centimeters to nanometers? (using the formula above)

5 cm = (5 × 10,000,000)

5 cm = 50,000,000 nm

## How Many Nanometers Are in a Centimeter?

There are 10,000,000 nanometers in a centimeter, that’s why we use this value in the formula above.

[1 cm = 10,000,000 nm]
