Ells to Centimeters (ell to cm)

1 ell equals 114.3 centimeters exactly.

1 ell = 114.3 centimeters

How to convert ells to centimeters

To convert ells to centimeters, multiply the number of ells by 114.3. This factor is exact. To go the other way, multiply centimeters by 0.008748906387 (rounded).

centimeters = ells × 114.3

Example: 10 ells = 1,143 centimeters.

About these units

Ell (ell)

Medieval EnglishHistorical unit (no longer in standard use)

45 inches (1.143 m). An English cloth measure, about the length of an arm. Other countries' ells ranged from about 0.46 m (Viking) to 1.37 m (the French aune).

Elbow and ell share a root: Old English eln meant the forearm, and the Latin ulna is a distant cousin. The ell began as an arm-length cubit, and later cloth ells grew longer. English tailors and drapers used one of 45 inches, a yard and a quarter, equal to 1.143 m, the figure used here. Edward I required every English town to keep an ell-wand as a standard rod for official measurement, and a surviving iron ell-wand hangs in a church on Gotland.

Each region had its own ell, which is why the unit is flagged as varying. A Scottish ell was about 37 inches (0.94 m), fixed in 1661 and abolished by the 1824 Weights and Measures Act. The Flemish ell was 27 inches (68.6 cm), and English importers of Dutch cloth bought by it. The French aune was about 137 cm, while German and Scandinavian ells were far shorter, from roughly 55 to 63 cm. Linen was sold by the English ell, but tapestry by the Flemish one.

1 ell = 1.143 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).
