Convert Centimeters to Nanometers
1 centimeter is 10,000,000 nm. One centimeter is exactly 10000000 nanometers.
One centimeter is 10000000 nanometers. To convert centimeters to nanometers, multiply by 10000000; to go the other way, divide by 10000000 or multiply by 1.0000 × 10^-7. The factor is exact rather than rounded: it follows from NIST. One hundredth of a meter, and the unit most of the world states height in.

Factors are entered by hand from NIST rather than derived from a units library, so the ones that terminate are exact rather than rounded.
The same converter answers this pair however it is written: centimetres to nanometres is the British spelling of the same units — the metre and the litre are spelled that way outside the United States and the quantity does not change.
How do you convert centimeters to nanometers? The converter and the working
- 1.Take the measurement in centimeters.
- 2.Multiply by 10000000 — that is how many nanometers fit in one centimeter.
- 3.To go back the other way, divide by 10000000, or multiply by 1.0000 × 10^-7.
Worked example: 25 centimeters to nanometers
- Formula
- cm × 10000000 = nm
- Arithmetic
- 25 × 10000000 = 250,000,000 nm
- Answer
- 25 cm = 250,000,000 nm
The factor is exact, so this figure is exact too — only the display is rounded.

What is a centimeter?
One hundredth of a meter, and the unit most of the world states height in.
What is a nanometer?
A billionth of a meter. Visible light runs from about 380 to 750 nm, and a semiconductor process node is named after one even though it stopped describing a physical dimension years ago.
How many nanometers are in a centimeter?
One centimeter is 10000000 nanometers, exactly. Going the other way, one nanometer is 1.0000 × 10^-7 centimeters. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
Every length unit here
The whole group — 13 units with their symbols and the size of each one in meters — is on the conversion index, along with every pair it makes. The table above already gives each of them relative to a centimeter.
