# Centimeters to nanometers

**1 centimeter in nanometers: 1 cm = 10,000,000 nm**

nm = cm × 10,000,000

To convert centimeters to nanometers, multiply by 10,000,000. The table below gives the values people look up most often, and the converter works for any number.

## How the conversion works

The relationship is nm = cm × 10,000,000. Both units measure length, so the conversion is a fixed factor that never changes.

## Common questions

### How many nanometers are in one centimeter?

One centimeter equals 10,000,000 nanometers. nm = cm × 10,000,000.

### How do you convert centimeters to nanometers?

Use nm = cm × 10,000,000. So 10 cm is 100,000,000 nm.

### How many centimeters are in one nanometer?

One nanometer equals 1 × 10^-7 centimeters, which is the reverse of the conversion above.
