Convert millimeters to nanometers (mm → nm)
1 millimeter = 1,000,000 nanometers. Multiply millimeters by 1,000,000 to get nanometers; divide nanometers by 1,000,000 to go back.

How to convert millimeters to nanometers
Step 1
Take the value in millimeters.
10 mm
Step 2
Multiply by 1,000,000.
10 × 1,000,000
Step 3
Round to the precision you need.
= 10,000,000 nm
The millimeter and the nanometer are both defined in terms of the metre and the kilogram, so this factor is exact, not an approximation.

Frequently asked questions
How many nanometers are in a millimeter?
There are 1,000,000 nanometers in one millimeter. Going the other way, one nanometer is 0.000001 millimeters.
How do I convert millimeters to nanometers?
Multiply the number of millimeters by 1,000,000. For example, 10 mm × 1,000,000 = 10,000,000 nm.
What is 5 millimeters in nanometers?
5 millimeters is 5,000,000 nanometers.
What is 100 millimeters in nanometers?
100 millimeters is 100,000,000 nanometers.
Is the millimeter to nanometer factor exact?
Yes. Both units are defined by international agreement in terms of the metre and the kilogram, so 1,000,000 is an exact factor and any error comes only from rounding the result.
