## Units

### 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.

### Millimeter (mm)

A metric unit of length equal to one thousandth of a meter. Used in engineering, manufacturing, and precise measurements.

## Background

A league is almost 5 million millimeters. A 1 mm grain of sand is 2.07 x 10-7 leagues. Verne's 20,000 leagues is about 96.6 billion millimeters. The millimeter makes league distances concrete in engineering terms.

## Good to Know

The millimeter is the working unit of engineering; the league is the poetic unit of adventure. Converting between them is like translating between technical manuals and epic novels: both describe the world, but in very different languages.

## FAQ

### How many millimeters are in 1 league?

One league contains approximately 4,828,032 mm (about 4.83 million).

### How many leagues are in 1 millimeter?

One millimeter equals approximately 2.07 x 10-7 leagues.

### When would I convert leagues to millimeters?

Never in practice. If you need to convert a literary distance to metric, meters or kilometers are the practical targets.

## Non-Frequently Asked Questions

### How many grains of sand span 1 league?

A medium grain of sand is about 0.5 mm. One league (4,828,032 mm) is about 9.66 million grains of sand. You could walk a league on a beach while stepping on roughly 10 million grains per step. Beaches are grainier than you think.

### How many millimeters of rain fall during a 1-league walk?

Light rain is about 2.5 mm per hour. A 1-league walk takes about 1 hour. So 2.5 mm of rain accumulates while you walk 4,828,032 mm forward. You move about 1.9 million times faster horizontally than the rain falls vertically. You are faster than rain.

### If I stacked coins to 1 league height, how many would I need?

A US quarter is 1.75 mm thick. One league (4,828,032 mm) requires about 2.76 million quarters, worth $690,000. A league-high coin tower would cost less than a house in San Francisco. The coin tower might also be more structurally sound.
