Links to Centimeters (li to cm)

1 link equals 20.1168 centimeters exactly.

1 link = 20.1168 centimeters

How to convert links to centimeters

To convert links to centimeters, multiply the number of links by 20.1168. This factor is exact. To go the other way, multiply centimeters by 0.04970969538 (rounded).

centimeters = links × 20.1168

Example: 10 links = 201.168 centimeters.

About these units

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).

Centimeter (cm)

Metric (SI)Current unit

One hundredth of a meter. Used for body measurements, clothing and everyday objects.

Scientists, rather than shopkeepers, gave the centimeter its place. In 1832 Carl Friedrich Gauss proposed a system of absolute units built on length, mass and time, choosing the millimeter, milligram and second. In 1873 a committee of the British Association for the Advancement of Science, whose members included James Clerk Maxwell and William Thomson (Lord Kelvin), recommended the centimeter, gram and second instead. That CGS system dominated physics for decades, until the metre-kilogram-second system replaced it in the mid-twentieth century and led to SI.

CGS units proved awkward for rooms and buildings, which run to hundreds of centimeters, but the centimeter itself never went away. It is still the everyday unit for height, clothing and small objects, and it appears in map scales and rainfall reports. An adult fingernail is roughly one centimeter wide, and a milliliter is defined as exactly one cubic centimeter. An inch is exactly 2.54 centimeters. The CGS system itself survives mainly in theoretical physics and astrophysics, where Gaussian units are still common.

1 centimeter = 0.01 meters (exactly).
