How to Convert Centimeters to Nanometers

To convert a measurement in centimeters to a measurement in nanometers, multiply the length by the following conversion ratio: 10,000,000 nanometers/centimeter.

Since one centimeter is equal to 10,000,000 nanometers, you can use this simple formula to convert:

nanometers = centimeters × 10,000,000

The length in nanometers is equal to the length in centimeters multiplied by 10,000,000.

For example, here's how to convert 5 centimeters to nanometers using the formula above.
nanometers = (5 cm × 10,000,000) = 50,000,000 nm

How Many Nanometers Are in a Centimeter?

There are 10,000,000 nanometers in a centimeter, which is why we use this value in the formula above.

1 cm = 10,000,000 nm

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

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

What Is a Centimeter?

One centimeter is equal to one-hundredth (1/100) of a meter, which is defined as the distance light travels in a vacuum in 1/299,792,458 of a second. One centimeter is equal to 0.393701 inches.

The centimeter, or centimetre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "centi" is the prefix for hundredths, or 10-2. Centimeters can be abbreviated as cm; for example, 1 centimeter can be written as 1 cm.

Metric rulers typically have 30 cm, which are represented by 30 large tick marks. To get a rough idea of the actual length of a centimeter, a standard number 2 pencil is just about 1 cm thick.

What Is a Nanometer?

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 billionths, or 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 a combination of both values, so make sure you get the correct type for your needs.
