**1 pc = 1.533880926137E+14 fur**

One parsec equals approximately 1.534 x 1014 furlongs (about 153 trillion). The parsec measures interstellar space; the furlong measures horse racing. The conversion factor of 153 trillion is the distance between professional astronomy and professional horse racing.

## Units

### 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.

### Furlong (fur)

Exactly 660 feet or one-eighth of a mile (201.168 m). Originally the length of a plowed furrow. Still used in horse racing.

## Background

A parsec is about 153 trillion furlongs. The Kentucky Derby (10 furlongs) covers 6.52 x 10-14 parsecs. Even the fastest horse covers a negligible fraction of a parsec per race.

## Good to Know

The furlong is the shortest commonly used distance unit (201 m). The parsec is among the longest (30.86 trillion km). Their ratio of 1014 spans the full range of human distance measurement from the racetrack to the galaxy. No two common units are farther apart in scale.

## FAQ

### How many furlongs are in 1 parsec?

One parsec contains approximately 1.534 x 1014 furlongs.

### How many parsecs is 1 furlong?

One furlong equals approximately 6.52 x 10-15 parsecs.

### Is this conversion used?

Never. Horse racing and astrophysics do not intersect.

## Non-Frequently Asked Questions

### How many Kentucky Derbys span the Milky Way?

The Milky Way (30,660 pc) is about 4.7 x 1018 furlongs = 4.7 x 1017 Derbys. If every star in the galaxy hosted a Derby simultaneously, you would still need each star to host about a million races. Galactic horse racing has scheduling problems.

### If Secretariat ran at light-speed, how long to cross 1 parsec?

Light takes 3.26 years to cross 1 parsec. Secretariat at light-speed would need 3.26 years. At his actual speed (about 37 mph / 16.5 m/s), Secretariat would need about 5.93 billion years. By then, the Sun would be a red giant. No roses for that finish.

### What is the ratio of the longest race to the shortest parsec?

The longest Thoroughbred race is about 2.5 miles (20 furlongs). The nearest stellar parsec is 1.3 pc = 2 x 1014 furlongs. Ratio: about 1013 (10 trillion). Horse racing covers one ten-trillionth of the nearest stellar distance. Horses are fast but not cosmic.
