What is a kilometer (km)?

Description:
The kilometer is the metric system's answer to long-distance measurement, ruling global roads and maps since the French Revolution.

Symbol: km
Common uses:

  • Road distance markers worldwide
  • Athletic track measurements
  • Geographical surveying

Definition:
Exactly 1,000 meters, or about 0.62137 miles. Part of the International System of Units (SI).

Conversion formula

For league to kilometer:
Kilometers = Leagues × 4.828

For kilometer to league:

Historical background

The leagues story begins with teh Roman Empire, where the "leuga" measured about 2.22 km. Medieval Europe then played telephone with the unit – the French "lieue" became 4 km, while Spanish explorers used a 5.573 km league to map the New World. It wasn't until international standardization efforts in the 19th century that 4.828 km became the agreed-upon value.

The kilometer entered the scene during the 1790s metric system revolution. French scientists defined it as 1/10,000 of the distance from equator to pole, though modern definitions now tie it to the speed of light. Talk about an upgrade!

  1. Texas' famous "Six Flags" refer to the six nations that ruled it, each using different league measurements during their reigns
  2. Arthurian legends reference "seven-league boots" that let wearers stride 54 km per step
  3. Uruguay still uses the "legua" (5.572 km) for rural property measurements
  4. 20,000 leagues = 96,560 km – enough to circle Earth twice at the equator
  5. The nautical league (5.556 km) remains an unofficial marine measurement
