# Nanometers to millimeters

**1 nanometer in millimeters: 1 nm = 0.000001 mm**

mm = nm × 0.000001

To convert nanometers to millimeters, multiply by 0.000001. The table below gives the values people look up most often, and the converter works for any number.

## How the conversion works

The relationship is mm = nm × 0.000001. Both units measure length, so the conversion is a fixed factor that never changes.

## Common questions

### How many millimeters are in one nanometer?

One nanometer equals 0.000001 millimeters. mm = nm × 0.000001.

### How do you convert nanometers to millimeters?

Use mm = nm × 0.000001. So 10 nm is 0.00001 mm.

### How many nanometers are in one millimeter?

One millimeter equals 1,000,000 nanometers, which is the reverse of the conversion above.
