**1 cm = 3.2407792894444E-19 pc**

One centimeter equals approximately 3.241 x 10-19 parsecs. A parsec (3.086 x 1016 m) contains about 3.086 x 1018 cm. The centimeter measures body and desk scale; the parsec measures distances between stars. About 19 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.

### Parsec (pc)

The distance at which one astronomical unit subtends an angle of one arcsecond. Approximately 3.26 light-years or 30.857 trillion kilometers. The standard unit in professional astronomy.

## Background

The nearest star at 1.3 parsecs is about 4.01 x 1018 cm away (4 quintillion centimeters). A 175 cm person is 5.67 x 10-17 parsecs tall. The centimeter and parsec represent the extremes of human measurement: touch versus telescope.

## Good to Know

The centimeter was defined on Earth. The parsec was defined by the stars. Together they bookend human measurement ambition: from the width of a fingertip to the gaps between suns.

## FAQ

### How many parsecs is 1 centimeter?

One centimeter equals approximately 3.241 x 10-19 parsecs.

### How many centimeters are in 1 parsec?

One parsec contains approximately 3.086 x 1018 cm (about 3.1 quintillion).

### Is this conversion useful?

No. These units serve completely different domains separated by 19 orders of magnitude.

## Non-Frequently Asked Questions

### If I measured the universe in centimeters, how big would the number be?

The observable universe is about 28.5 gigaparsecs across, which is about 8.8 x 1028 cm. That number has 29 digits. Your ruler has 30 of the markings that would need to be laid end-to-end 2.9 octillion times. Big numbers are the universe's love language.
