What is a Hectometer and a Ell?

The hectometer (symbol: hm) is a unit of length in the metric system. It is defined as exactly one hundred (100) meters, which is the base unit of length in the International System of Units (SI). Therefore, 1 kilometer equals 10 hectometers.

The Ell is an historical unit of length, primarily used for measuring cloth and textiles. Its exact length varied considerably depending on the region, country, and time period, making it a non-standardized unit overall, though often legally defined within specific jurisdictions.

It is generally understood to have originated from the length of the arm or forearm, similar to the cubit. The name itself derives from the Proto-Germanic word *alinō, meaning "forearm".

Common historical values demonstrate this variability:

  • English Ell: Traditionally 45 inches (1.25 yards, exactly 1.143 meters). This was the most common ell in England, particularly for measuring imported Flemish cloth.
  • Scottish Ell: Approximately 37.06 inches (about 0.941 meters), based on the standard Scottish inch.
  • Flemish (or Brabant) Ell: Approximately 27 inches (about 0.686 meters). Widely used in the Low Countries, a major center for textile production.
  • French Ell (Aune): Varied, but often around 46.77 inches (about 1.188 meters) in Paris. The aune itself had different lengths in different French regions.
  • Polish Ell (Łokieć): Approximately 22.7 inches (about 0.576 meters).
  • Swedish Ell (Aln): Approximately 23.3 inches (about 0.593 meters).

Note: The Hectometer is part of the metric (SI) system, primarily used globally in science and trade. The Ell belongs to the imperial/US customary system.

History of the Hectometer and Ell

The hectometer originates from the French Revolution era, alongside the development of the metric system in the 1790s. The system aimed for rational, decimal-based units derived from the meter. The prefix "hecto-" (derived from Greek "hekaton" meaning hundred) signifies a factor of one hundred (10²). While the meter and kilometer became the more common standards for many applications, the hectometer was defined as part of the systematic decimal structure of the metric system.

The ell was a fundamental unit for the textile trade across Europe, flourishing from the medieval period through the early modern era and into the 19th century. Its origins likely lie in anthropomorphic measurements related to the arm, similar to the cubit.

The lack of a universal standard led to numerous regional variations. Different cities, guilds, or nations established their own "standard" ell, often physically represented by a metal rod kept by authorities. This variation could sometimes be a source of trade disputes but also reflected local manufacturing and trade practices.

The English ell of 45 inches (longer than the standard English yard of 36 inches) became particularly well-established, possibly to account for shrinkage or to provide a customary "bonus" measure when selling cloth.

With the rise of standardized measurement systems like the Imperial system (promoting the yard) and especially the Metric system (introducing the meter), the ell gradually became obsolete during the 18th and 19th centuries. Legal reforms in many countries formally abolished it in favor of metric units.

Common Uses for hectometers and ells

Explore the typical applications for both Hectometer (metric) and Ell (imperial/US) to understand their common contexts.

Common Uses for hectometers

The hectometer is not frequently used in everyday language or general measurements compared to meters or kilometers. However, it finds niche applications in specific fields:

  • Agriculture and Forestry: Sometimes used for measuring land parcel dimensions or distances in large fields or forests where measurements are typically in the hundreds of meters.
  • Surveying: Can be used in land surveying, particularly in contexts where metric units are standard but kilometers are too large and meters too small for convenient expression of certain distances.
  • Meteorology: While not a length unit, the related unit hectopascal (hPa), using the same prefix, is the standard international unit for atmospheric pressure.
  • Radio Astronomy: Certain radio wavelengths might be expressed in hectometers.
  • Education: Useful in teaching the metric system to illustrate the powers of 10 and the relationship between different metric length units (1 km = 10 hm = 100 dam = 1000 m).

Common Uses for ells

The ell is now obsolete but was historically crucial for:

  • Textile Trade: Its primary and defining use was measuring and selling lengths of cloth (wool, linen, silk, etc.). Cloth was often priced and sold "by the ell".
  • Tailoring and Dressmaking: Used by artisans creating garments.
  • Mercantile Records: Appears frequently in historical merchant accounts, inventories, customs documents, and trade records. Understanding the local ell is vital for interpreting these economic historical sources.
  • Land Measurement (Rarely): In some specific, localized contexts, an ell might have been used for land, but this was uncommon compared to units like the rod or chain.
  • Literature and Culture: Referenced in historical texts, literature, and idioms (e.g., "Give him an inch, and he'll take an ell").

Frequently Asked Questions

Questions About Hectometer (hm)

How many hectometers are in a kilometer?

There are exactly 10 hectometers in 1 kilometer.

How many meters are in a hectometer?

There are exactly 100 meters in 1 hectometer.

How many decameters are in a hectometer?

There are exactly 10 decameters (dam) in 1 hectometer.

How do you convert hectometers to miles?

To convert hectometers to miles, multiply the number of hectometers by approximately 0.0621371. For example, 5 hm is about 5 * 0.0621371 = 0.3106855 miles.

Is the hectometer commonly used?

No, the hectometer is one of the less commonly used metric units in everyday practice. Meters and kilometers are generally preferred for most practical distance measurements.

Why isn't the hectometer used more often?

For many everyday distances (room sizes, building heights), meters provide a convenient scale. For longer distances (travel, road signs), kilometers are more practical. The hectometer often represents an intermediate scale (100 meters, roughly the length of a football field) that doesn't align as frequently with common measurement needs as meters or kilometers do.

About Ell (ell)

How long is an Ell?

There is no single fixed length for the ell; it varied significantly by location and time. Some key examples include:

  • English Ell: 45 inches (1.143 m)
  • Scottish Ell: ~37 inches (~0.94 m)
  • Flemish Ell: ~27 inches (~0.69 m)
  • French Aune (Ell): ~47 inches (~1.19 m) Always check the context (region and era) when encountering a measurement in ells. The English ell of 45 inches is often assumed in English-language historical contexts unless otherwise specified.

How does the Ell compare to a Yard?

The English ell (45 inches) is exactly 1.25 times longer than the standard yard (36 inches). However, other ells could be shorter (like the Flemish ell) or have different relationships to the local yard equivalent.

Is the Ell related to the Elbow or Arm?

Yes, the name "ell" derives from Proto-Germanic *alinō ("forearm"), cognate with Latin ulna and Greek ōlénē, all referring to the forearm or elbow. This strongly suggests an origin based on the length of the human arm, similar to the cubit. However, the standardized lengths adopted for trade were often considerably longer than a literal forearm.

Why did the Ell length vary so much?

The variation stemmed from:

  • Lack of Universal Standards: Before the metric system, measurement standards were highly localized.
  • Regional Customs: Different areas developed their own traditional lengths based on local needs and practices.
  • Trade Protectionism: Sometimes, variations were maintained deliberately by guilds or cities.
  • Evolution Over Time: The definition could change even within the same region over centuries.

Is the Ell an SI unit?

No, the ell is not part of the International System of Units (SI). It is an historical, customary unit belonging to various pre-metric systems. The corresponding SI unit for length is the meter (m).

Is the Ell still used today?

No, the ell is obsolete and is not used for any standard commercial, scientific, or practical measurements today. Its use was superseded primarily by the yard (in Imperial/US customary systems) and the meter (in the metric system). Its relevance is now purely historical.
