Nanometers to Millimeters Conversion
Enter the length in nanometers below to get the value converted to millimeters.
How to Convert Nanometers to Millimeters
To convert a nanometer measurement to a millimeter measurement, divide the length by the conversion ratio.
Since one millimeter is equal to 1,000,000 nanometers, you can use this simple formula to convert:
The length in millimeters is equal to the nanometers divided by 1,000,000.

Our inch fraction calculator can add nanometers and millimeters together, and it also automatically converts the results to US customary, imperial, and SI metric values.
Nanometers and millimeters are both units used to measure length. Keep reading to learn more about each unit of measure.
Nanometers
One nanometer is equal to one-billionth (1/1,000,000,000) of a meter, which is defined as the distance light travels in a vacuum in a 1/299,792,458 second time interval.
The nanometer, or nanometre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "nano" is the prefix for 10-9. Nanometers can be abbreviated as nm; for example, 1 nanometer can be written as 1 nm.
The nanometer is an extremely small unit of length measurement, often used to measure things that are very small, such as the transistors and electrical pathways in computer processors and nanotechnology.
Millimeters
One millimeter is equal to one-thousandth (1/1,000) of a meter, which is defined as the distance light travels in a vacuum in a 1/299,792,458 second time interval.
The millimeter, or millimetre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "milli" is the prefix for 10-3. Millimeters can be abbreviated as mm; for example, 1 millimeter can be written as 1 mm.
Millimeters are often represented by the smallest ticks on most metric rulers. To get a reference point of the size, the thickness of a US dime is 1.35mm.[1]
We recommend using a ruler or tape measure for measuring length, which can be found at a local retailer or home center. Rulers are available in imperial, metric, or combination with both values, so make sure you get the correct type for your needs.
