What is a Skein and a Smoot?
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 Smoot is a non-standard, humorous unit of length created as part of an MIT fraternity prank in October 1958. It is defined by the height of Oliver R. Smoot (MIT class of 1962) at the time of the prank, which was 5 feet 7 inches.
This equates to:
- 67 inches (in)
- 1.7018 meters (m)
- Approximately 1.86 yards (yd)
Unlike standardized units, the Smoot is intrinsically tied to a specific individual's height at a particular moment and serves primarily as a cultural artifact and inside joke, particularly within the MIT community.
Note: The Skein is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Smoot belongs to the imperial/US customary system.
History of the Skein and Smoot
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 Smoot unit originated in October 1958 during the pledge activities of the Lambda Chi Alpha fraternity at MIT. Pledges were tasked with measuring the length of the Harvard Bridge, which connects Boston and Cambridge, Massachusetts, over the Charles River.
Instead of using conventional measuring tools, the fraternity members decided to use one of their pledges, Oliver Smoot, as the unit of measure. They repeatedly laid him down end-to-end across the bridge, marking off increments in paint. His companions carried him or helped him move for each new measurement.
The final measurement determined the bridge's length to be 364.4 Smoots "plus or minus one ear". The "ear" indicated the uncertainty of the measurement, adding to the absurdity and humor of the event.
The painted markings on the bridge became a local landmark. They have been maintained and periodically repainted over the decades, often unofficially by members of the fraternity or other MIT affiliates. The Cambridge Police Department traditionally tolerates the markings because, among other reasons, they serve as useful reference points for identifying locations along the bridge.
Interestingly, Oliver R. Smoot later became a prominent figure in standards organizations, serving as Chairman of the American National Standards Institute (ANSI) and President of the International Organization for Standardization (ISO), an ironic twist given his namesake unit's non-standard nature.
Common Uses for skeins and smoots
Explore the typical applications for both Skein (imperial/US) and Smoot (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 smoots
The Smoot is not used for any official, scientific, or commercial measurements. Its use is primarily cultural and humorous:
- Harvard Bridge Markings: The painted markings on the bridge sidewalk are its most famous application, indicating distance in Smoots from the Boston side. They are a well-known local landmark.
- MIT Culture and Slang: Used humorously within the MIT community and sometimes in the broader Boston area as a quirky local reference.
- Digital Recognition: The unit gained wider recognition when it was included as a unit of measurement in Google Calculator and Google Earth's ruler tool.
- Popular Culture: Occasionally referenced in media or tech circles as an example of a non-standard or humorous unit.
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 Smoot (smoot)
How long is a Smoot?
One Smoot is exactly the height of Oliver R. Smoot in 1958:
- 5 feet 7 inches
- 67 inches
- 1.7018 meters
Is the Smoot an official or standardized unit?
No, the Smoot is not an official or standardized unit of measurement in any system (Imperial, US customary, or SI). It is a non-standard, humorous unit originating from a specific event.
Why is the bridge measurement "plus or minus one ear"?
The "plus or minus one ear" (often written as ± εar) reflects the humorous imprecision of the original measurement method using a person. It signifies the margin of error in a whimsical way, possibly referencing the difficulty of the final partial measurement or simply adding to the prank's absurdity.
Are the Smoot markings still on the Harvard Bridge?
Yes, the markings are traditionally repainted periodically (often by Lambda Chi Alpha members) and are considered a fixture of the bridge. During bridge renovations in 2011, the Massachusetts Department of Transportation restored the markings, acknowledging their cultural significance.
How does the Smoot compare to standard units?
- 1 Smoot = 1.7018 meters
- 1 Meter ≈ 0.5876 Smoots
- 1 Smoot = 5.583 feet (5 feet 7 inches)
- 1 Foot ≈ 0.1791 Smoots
Is the Smoot an SI unit?
No, the Smoot is not an SI unit. It is a non-standard, informal unit. The SI base unit for length is the meter (m).
What did Oliver Smoot think of the unit?
Oliver Smoot generally embraced his namesake unit with good humor throughout his life and career, often participating in events related to it at MIT.
