**1 nmi = 6.001923244051E-14 pc**

One nautical mile equals approximately 6.002 x 10-14 parsecs. A parsec contains about 1.666 x 1013 NM (16.7 trillion). The NM navigates Earth's oceans; the parsec navigates interstellar space.

## Units

### Nautical Mile (nmi)

Exactly 1852 meters by international agreement. Based on one minute of arc of latitude at the Earth's surface. The standard unit for maritime and air navigation.

### 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

Proxima Centauri at 1.3 parsecs is about 21.66 trillion NM. A circumnavigation (21,600 NM) is about 1.3 x 10-9 parsecs - a billionth of the nearest star's distance. Even sailing around the world leaves you cosmically at home.

## Good to Know

The NM was born from Earth's geometry (1 arcminute of latitude). The parsec was born from stellar geometry (1 arcsecond of parallax). Both are geometric units defined by angular measurement. The NM measures angles on Earth's surface; the parsec measures angles to the stars. Same mathematical principle, 13 orders of magnitude apart.

## FAQ

### How many parsecs is 1 NM?

One NM equals approximately 6.002 x 10-14 parsecs.

### How many NM are in 1 parsec?

One parsec contains approximately 1.666 x 1013 NM (about 16.7 trillion).

### Is this conversion used?

Never. Ocean navigation and interstellar measurement have no practical overlap.

## Non-Frequently Asked Questions

### How many circumnavigations equal 1 parsec?

A circumnavigation is 21,600 NM. 1 parsec is 16.66 trillion NM. That is about 771 million laps around Earth. At 1 circumnavigation per year, it would take 771 million years. Complex life has existed for about 540 million years. You would need 1.43 complex-life-eras of sailing.

### If Columbus had sailed toward Proxima Centauri, where would he be?

Columbus sailed about 3,000 NM in 1492. If he continued for 534 years at 3,000 NM/year, he would have covered 1.6 million NM. Proxima Centauri is 21.66 trillion NM away. He would have covered 0.0000074% of the distance. At that rate: 2.9 billion more years to go. Fair winds needed.

### Has humanity's total ocean sailing reached 1 parsec?

Humanity has probably sailed about 100 trillion NM in total maritime history. 1 parsec is 16.66 trillion NM. So yes - all of human sailing equals about 6 parsecs. Our collective ocean voyaging has theoretically reached nearby stars. Just not in any single direction. Entropy makes bad navigators.
