About these units

Kilometer (km)

Metric (SI)Current unit

1,000 meters. The standard unit for road distances in most countries.

A name for 1,000 meters took a while to settle. In 1793 France's National Convention made the metre the sole French unit of length, and the first proposed name for the thousand-metre multiple was millaire. Everyday French usage then leaned on the myriametre, 10,000 meters, well into the 1800s. The Netherlands adopted the kilometre in 1817, under the local name mijl, and made it the only official unit of that size in 1867. In 1935 the CIPM dropped the myria- prefix, which left the kilometre as the standard unit for road-scale distances.

Kilo- is the SI prefix for a thousand, and the kilometre is now the preferred unit for land distances in most of the world, with the United States, the United Kingdom and Liberia among those that still use the mile. One kilometre is about 0.621 mile. The main span of Lisbon's 25 de Abril Bridge, at 1.013 km, gives a sense of the scale. Even its pronunciation has been argued over: in 1970 Australia's Metric Conversion Board made stress on the first syllable official, although Prime Minister Gough Whitlam argued for stress on the second. Military slang in several countries calls it a klick.

1 kilometer = 1,000 meters (exactly).

Link (li)

US & ImperialTraditional unit (still used in some regions)

One hundredth of a chain, 7.92 inches (0.201168 m). A surveying unit, one link of Gunter's chain.

Each link is the small piece that makes up a surveyor's chain, and the chain's hundred links gave decimal fractions to a system built on feet and yards. A single link measures 7.92 inches, or exactly 0.201168 m, because it is one hundredth of a 66-foot chain. Because of that, distances could be recorded in whole chains and links without fractions.

Edmund Gunter introduced the 100-link chain in England in 1620, and the link spread across the English-speaking world with it. Twenty-five links make a rod, 1,000 make a furlong and 8,000 make a mile. The exact size depends on which foot is used: the pre-1959 imperial foot gives about 201.1677 mm, the US survey foot about 201.1684 mm, and the international foot exactly 201.168 mm. Since the US survey foot was retired after 2022, the international value applies there too. Metric and electronic surveying replaced links in the twentieth century, though old deeds still use them.

1 link = 0.201168 meters (exactly).
