# mm to nm

In this article, we’ll discuss the conversion process of mm (millimeter) to nm (nanometer). So that you’ll get your solution in a simple and convenient way.

## Some Key Points about mm and nm :

Millimeter is the most widely used units of length which equals to 1/1000th of a meter and nanometer is also a unit of **length** or **distance**, equals to 1/1000000000. Both are the units of **SI**, applicable for measuring small distances and small length. According to SI rules, the unit symbol for millimeter is ‘mm’ and for nanometer it is ‘nm’.

Since, There are 1000000 nanometer in a millimeter.

Or 1 Millimeter is equal to 1000000 Nanometer.

[1 mm = 1000000 nm]

## The conversion process from mm to nm

You can use **two methods** to do the conversion –

1. By using Converter

2. By using Formula

Here we’ll explain both the methods so you’ll get more clarity about your problem.

### Method 1. – By using mm to nm converter

This is a very easy to use millimeter to nanometer converter. Firstly, you need to just type the millimeter (mm) value in the text field of the conversion form to start converting mm to nm.

Now, select the decimals value and finally choose convert button if auto calculation didn’t work. Nanometer value will be converted automatically as you type. After that you’ll get your results.

[The decimals value(as shown) is the number of digits to be calculated or rounded of the result of millimeter to nanometer conversion.]

### Method 2. – By using formula

To convert a millimeter measurement to a nanometer measurement, we need to multiply the length by the conversion ratio.

Since, one millimeter is equal to 1,000,000 nanometers, you can use this simple formula to convert:

**nanometers** = **millimeters** × **1,000,000**

As we can see, The length in nanometers is equal to the millimeters multiplied by 1,000,000.

Let’s take an example,

Here’s, how to convert 3 millimeters to nanometers using the formula above.

3 mm = (3 × 1,000,000) = 3,000,000 nm
