How to Convert Millimeters to Nanometers

conversion scale showing millimeters and equivalent nanometers length values

To convert a millimeter measurement to a nanometer measurement, multiply the length by the conversion ratio. One millimeter is equal to 1,000,000 nanometers, so use this simple formula to convert:

nanometers = millimeters × 1,000,000

The length in nanometers is equal to the millimeters multiplied by 1,000,000.

For example, here's how to convert 5 millimeters to nanometers using the formula above.
5 mm = (5 × 1,000,000) = 5,000,000 nm

Our inch fraction calculator can add millimeters and nanometers together and it also automatically converts the results to US customary, imperial and SI metric values.

Millimeters and nanometers are both units used to measure length. Keep reading to learn more about each unit of measure.

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]

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.

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.

If you need a ruler you can also download and print our free printable rulers, which include both imperial and metric measurements.
