What is a Skein and a Aln?
A Skein is a traditional unit of length primarily used for measuring yarn or thread. It represents a specific length of yarn coiled into a loop, often then twisted for packaging and sale.
The length of a skein is highly variable and depends significantly on the type of fiber (e.g., cotton, wool, linen), the region, and the specific yarn count system being used. There is no single universal standard.
Common historical or industry-specific standard lengths include:
- Cotton Skein (or Hank): 840 yards (≈ 768.1 meters)
- Worsted Wool Skein (or Hank): 560 yards (≈ 512.1 meters)
- Linen Skein (or Lea): 300 yards (≈ 274.3 meters)
For the purpose of this converter, a Skein is defined as:
- Exactly 120 yards (yd)
- Exactly 109.728 meters (m)
- Exactly 360 feet (ft)
This value (120 yards) corresponds to a Lea, a unit often associated with linen and sometimes used as a subdivision or specific standard in certain yarn count systems.
The Aln (Swedish), Alen (Danish and Norwegian) was a traditional Scandinavian unit of length, analogous to the English ell or cubit. Its length varied significantly by region and time but was generally based on the length of the forearm.
Key standardized or common values include:
- Swedish Aln: Officially standardized (as the Rydaholmsaln) in 1665 and confirmed in 1735 as exactly 2 Swedish fot (feet). This equates to approximately 0.5938 meters (or 59.38 cm / 23.38 inches).
- Danish Alen: The common standard (Sjællandsk alen) was 2 Danish fod (feet), equating to approximately 0.6277 meters (or 62.77 cm / 24.71 inches).
- Norwegian Alen: Often followed the Danish standard due to political union. After 1824, it was legally defined as 2 Norwegian fot, equating to 0.6275 meters (or 62.75 cm / 24.70 inches), very close to the Danish value.
The Aln/Alen was typically subdivided into 4 kvarter (quarters).
Note: The Skein is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Aln belongs to the imperial/US customary system.
History of the Skein and Aln
The practice of winding yarn into standardized lengths like skeins or hanks dates back centuries. It originated as a practical way to manage, measure, dye, trade, and store yarn. Standardizing the length allowed spinners, weavers, and merchants to calculate material quantities and costs more reliably.
Different textile industries and regions developed their own specific standards for skein lengths. These standards became intrinsically linked to yarn count systems (e.g., Cotton Count (Ne), Worsted Count (Nw), Linen Count (NeL)), which define the fineness (thickness) of yarn based on the length per unit weight (e.g., the number of 840-yard hanks per pound for cotton).
While metric units (meters, kilograms) are now standard for trade, the historical skein lengths remain relevant for understanding yarn counts and for crafts like knitting and crochet where yarn is still often sold in skeins or hanks labeled with length and weight.
The Aln/Alen originates from the Proto-Germanic word for forearm (alinō), reflecting its basis as an anthropomorphic unit, similar to the cubit in other cultures. For centuries, its length was inconsistent, varying between regions, cities, and trades within Sweden, Denmark, and Norway.
- Early Variations: Numerous local standards existed, often based on physical rods kept by authorities or guilds.
- Standardization Efforts:
- Sweden: Attempts at standardization culminated in the adoption of the Rydaholmsaln (based on a specific iron standard bar from Rydaholm church) in 1665, defined as 2 fot. This standard (≈0.5938 m) became mandatory nationwide in 1735.
- Denmark & Norway: The Sjællandsk alen (Zealand ell, ≈0.6277 m) became the dominant standard in Denmark and, consequently, in Norway during their union. Norway later formally adopted a slightly different value (≈0.6275 m) based on its own fot definition in 1824.
- Metrication: The Aln/Alen was officially replaced by the metric system during the 19th and early 20th centuries: Norway in 1875, Sweden in 1889, and Denmark in 1907.
Common Uses for skeins and alnar
Explore the typical applications for both Skein (imperial/US) and Aln (imperial/US) to understand their common contexts.
Common Uses for skeins
Historically and currently, the skein (or the concept of a standard yarn length) is used in:
- Textile Industry: Calculating yarn yield, planning weaving or knitting projects, and defining yarn counts.
- Yarn Sales: Yarn for handcrafts (knitting, crochet) is commonly sold in skeins or hanks, usually labeled with weight, length (in yards or meters), and fiber type.
- Dyeing: Skeins are a convenient form for dyeing batches of yarn evenly.
- Historical Context: Understanding older textile production methods, trade practices, and calculations.
Common Uses for alnar
Historically, the Aln/Alen was a fundamental unit for everyday trade and craft:
- Textiles: Its most prominent use was measuring cloth (wool, linen, silk). Standardization was often driven by the textile trade.
- Timber and Lumber: Measuring lengths of wood.
- Rope and Cordage: Measuring lengths of rope.
- Construction: Used in building measurements, though perhaps less formally than in trade.
- General Trade: Measuring various goods sold by length.
It was less commonly used for land surveying, where units like the stång (rod) or mil (mile) were preferred.
Frequently Asked Questions
Questions About Skein (skein)
How long is a skein?
The length varies greatly! There is no single universal value. Common standards include:
- Cotton: 840 yards (≈ 768 m)
- Worsted Wool: 560 yards (≈ 512 m)
- Linen (Lea): 300 yards (≈ 274 m)
- Value used in this converter: 120 yards (≈ 110 m), representing a specific standard sometimes called a Lea.
Always check the specific fiber type or context when dealing with skeins.
How is a skein different from a hank or a ball of yarn?
- Skein / Hank: These terms are often used interchangeably. They refer to yarn wound into a large loop, which is usually twisted for sale. This form is good for dyeing and storage but must be wound into a ball before use to prevent tangling.
- Ball: Yarn wound into a spherical or oval shape, ready for direct use in knitting or crocheting.
Sometimes "skein" is used informally to refer to any package of yarn.
What is yarn count and how does it relate to skeins?
Yarn count is a measure of the fineness (thickness) of yarn. Most systems define it based on length per unit weight. Standard skein/hank lengths are fundamental to these systems. For example:
- Cotton Count (Ne): The number of 840-yard hanks that weigh one pound. Higher Ne means finer yarn.
- Worsted Count (Nw): The number of 560-yard hanks that weigh one pound.
- Linen Count (NeL or Lea): The number of 300-yard leas that weigh one pound.
Is the Skein an SI unit?
No, the Skein is not an SI unit. It is a traditional, variable unit used in the textile industry. The SI base unit for length is the meter (m). Yarn length is typically measured in meters or yards in modern contexts.
About Aln (aln)
How long is an Aln/Alen?
There isn't one single value, as it depended on the country and era. The main official standards were:
- Swedish Aln: ~0.594 meters / ~23.4 inches
- Danish Alen: ~0.628 meters / ~24.7 inches
- Norwegian Alen: ~0.628 meters / ~24.7 inches (very close to Danish)
Always consider the context (Swedish, Danish, or Norwegian) when encountering this unit in historical documents.
What's the difference between the Aln in different countries?
The primary difference was length:
- The Swedish Aln (≈59.4 cm) was noticeably shorter than the Danish and Norwegian Alen (both ≈62.8 cm).
- All were typically defined as 2 local fot (feet), but the length of the fot itself varied between the countries.
Is the Aln related to the English Ell?
Yes, both the Aln/Alen and the English Ell are historical units of length derived from the concept of the cubit or forearm length (Latin ulna). However, their standardized lengths differed significantly. The most common English Ell was 45 inches (1.143 m), much longer than any standard Scandinavian Aln/Alen.
Is the Aln/Alen still used today?
No, the Aln/Alen is obsolete. It was officially replaced by the meter in Sweden, Denmark, and Norway during the metrication process in the late 19th and early 20th centuries. Its use today is purely historical.
Is the Aln an SI unit?
No, the Aln/Alen is not an SI unit. It is a traditional unit from the historical Scandinavian systems of measurement. The SI base unit for length is the meter (m).
