# Centimeters to Nanometers (cm to nm)

Source: https://www.unitconvertercalculator.com/length/centimeters-to-nanometers/

**1 cm = 10000000 nm**

One centimeter equals exactly 10,000,000 nanometers (107 nm). The centimeter measures visible everyday objects; the nanometer measures chip transistors, DNA, and molecular structures. Seven orders of magnitude separate them.

## Units

### Centimeter (cm)

A metric unit of length equal to one hundredth of a meter. Commonly used for body height, clothing sizes, and everyday measurements.

### Nanometer (nm)

One billionth of a meter. Used to measure wavelengths of light, semiconductor chip features, and molecular structures.

## Background

A centimeter contains 10 million nanometers. A 3 nm chip transistor is 3 x 10-7 cm. A DNA molecule at 2.5 nm is 2.5 x 10-7 cm wide. A human fingernail (1 cm) contains about 10 million nanometers of width.

## Good to Know

When Apple says 'A17 Pro chip with 3-nanometer technology,' they mean each transistor gate is about 3 nm wide. Your 15 cm phone screen (1.5 x 108 nm) contains transistors 50 million times smaller than the screen itself.

## FAQ

### How many nanometers are in 1 centimeter?

One centimeter contains exactly 107 nanometers (10 million nm).

### How do I convert cm to nm?

Multiply centimeters by 10,000,000 (107).

### When is this conversion used?

In nanotechnology and materials science when relating visible sample dimensions (cm) to nanoscale features being measured.

## Non-Frequently Asked Questions

### How many chip wire bonds span a thumb?

A chip wire bond is about 25,000 nm (1 thou) in diameter. A thumb is about 20 mm = 20,000,000 nm. About 800 wire bonds span your thumb. These gold or copper wires connect nm-scale transistors to mm-scale package pins. Wire bonds are the bridge between the nano and macro worlds.
