**1 ly = 1959541791061.2 lea**

One light-year equals approximately 1.960 x 1012 leagues (about 2 trillion). The light-year measures distances between stars; the league (3 miles / 4.83 km) measures literary walking distances. A light-year is about 2 trillion walking-hours.

## Units

### Light-year (ly)

The distance light travels in one Julian year (365.25 days) in vacuum. Exactly 9,460,730,472,580,800 meters. Used for interstellar distances.

### League (lea)

Exactly 3 statute miles (4828.032 m). A historical unit of distance, often associated with the distance a person could walk in one hour.

## Background

Proxima Centauri at 4.24 light-years is about 8.31 trillion leagues away. Verne's 20,000 leagues is only 1.02 x 10-8 light-years. The entire circumference of Earth is about 8,302 leagues or 0.000042 light-years. The light-year dwarfs all earthly distances.

## Good to Know

The league measures the oldest form of human travel: walking. The light-year measures the fastest phenomenon in physics: light. Between them lies the entire history of human ambition to go faster and farther.

## FAQ

### How many leagues are in 1 light-year?

One light-year contains approximately 1.960 x 1012 leagues (about 2 trillion).

### How many light-years is 1 league?

One league equals approximately 5.103 x 10-13 light-years.

### How do leagues compare to light-years?

A light-year is about 2 trillion leagues. Since a league is roughly 1 hour of walking, a light-year is about 2 trillion walking-hours - roughly 228 million years of non-stop walking.

## Non-Frequently Asked Questions

### How many Verne voyages fit in 1 light-year?

Verne's 20,000 leagues = 1.02 x 10-8 light-years. So about 98 million Nautilus voyages fit in 1 light-year. Nemo would need to repeat his entire adventure 98 million times. Even an immortal submarine captain would lose interest.

### How many walking-years is 1 light-year?

At 1 league per hour, 24 hours a day: 1.96 x 1012 leagues / (24 x 365) = about 228 million years of non-stop walking. Homo sapiens has existed for about 300,000 years. You would need to walk 760 times longer than our species has existed.

### If Middle-earth were real, would any quest span a light-year?

Tolkien's longest journey (Shire to Mordor) is about 280 leagues = 1.43 x 10-10 light-years. To cover 1 light-year of quest, you would need about 7 billion Shire-to-Mordor trips. Even Sauron does not have that kind of time.
