What is a Chi (Chinese) and a Skein?
The Chi (尺) is a traditional Chinese unit of length, often translated as the "Chinese foot". It served as a fundamental base unit within the traditional Chinese system of weights and measures (度量衡, dùliànghéng).
The Chi is traditionally subdivided and multiplied as follows:
- 1 Zhang (丈) = 10 Chi
- 1 Chi (尺) = 10 Cun (寸 - Chinese inch)
- 1 Cun (寸) = 10 Fen (分 - Chinese line)
While sometimes called the "Chinese foot", its length has historically varied significantly and is generally longer than the imperial foot. The modern standardized value is exactly 1/3 of a meter.
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.
Note: The Chi (Chinese) is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Skein belongs to the imperial/US customary system.
History of the Chi (Chinese) and Skein
The Chi has been used in China for millennia, with its length undergoing numerous changes across different dynasties and regions. Archaeological evidence suggests its use dates back to the Shang Dynasty (c. 1600–1046 BC).
- Early Dynasties: Lengths varied, often based on standards set by the ruling government. For example, the Chi during the Han Dynasty (206 BC – 220 AD) was around 23.1 cm, while during the Tang Dynasty (618–907 AD), it was closer to 30.7 cm.
- Later Dynasties: Variations continued. During the Qing Dynasty (1644–1912), different standards existed for different trades, such as a gongchéng chi (工尺) for engineering (approx. 32 cm) and a cáiféng chi (裁縫尺) for tailoring (approx. 35.5 cm).
- 20th Century Standardization: In the Republic of China era (1912–1949), efforts were made to standardize traditional units with the metric system. In 1929, the Chi was officially defined as exactly 1/3 of a meter (33.33... cm). This standard was largely retained by the People's Republic of China after 1949.
Unlike some Western units (like the foot or digit), the Chi's connection to direct anthropomorphic measurement (like the length of a forearm or foot) is less clear and likely became conventionalized early in its history.
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.
Common Uses for chi and skeins
Explore the typical applications for both Chi (Chinese) (imperial/US) and Skein (imperial/US) to understand their common contexts.
Common Uses for chi
Historically, the Chi was ubiquitous in Chinese society. Its modern usage is less common but persists in specific areas:
- Historical Measurement: Essential for understanding dimensions in ancient and imperial Chinese architecture, engineering projects (like canals and walls), land surveying (often in conjunction with the Bu 步 and Li 里), and everyday objects.
- Textile Measurement: Used for measuring cloth lengths, similar to the Western ell or yard. The tailor's chi (裁縫尺) was specifically used for this.
- Traditional Crafts: Still used in some traditional arts and crafts, such as calligraphy, painting, furniture making, and seal carving, where traditional proportions are valued.
- Traditional Chinese Medicine (TCM): The cun (1/10th of a chi) is used as a proportional body measurement unit (known as the body inch) to locate acupuncture points. The patient's own body proportions determine the length of their cun.
- Cultural Context: Appears frequently in historical texts, literature, idioms (e.g., 得寸進尺, dé cùn jìn chǐ - "gain an inch, advance a foot," meaning to become greedy), and cultural practices.
- Informal Measurement: In some contexts, particularly among older generations or in rural areas, informal measurements might still reference the chi or cun.
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.
Frequently Asked Questions
Questions About Chi (Chinese) (chi)
How long is a Chi?
The length of the Chi has varied significantly throughout history. Key values include:
- Han Dynasty: ~23.1 cm (~9.1 inches)
- Tang Dynasty: ~30.7 cm (~12.1 inches)
- Modern Standardized Value (since 1929): Exactly 1/3 of a meter.
- This equals 33.33... centimeters (cm).
- Approximately 13.12 inches (in).
- Approximately 1.094 feet (ft).
What are the subdivisions and multiples of the Chi?
The traditional system is decimal:
- Subdivisions: 1 Chi = 10 Cun (寸); 1 Cun = 10 Fen (分).
- Multiples: 1 Zhang (丈) = 10 Chi. Another important related unit is the Li (里), standardized as 150 Zhang or 1500 Chi (historically varied, now 500 meters).
How does the Chi relate to the Meter?
Since 1929, the Chi has been officially defined in relation to the meter:
- 1 Chi = 1/3 Meter
- 1 Meter = 3 Chi
Is Chi related to other East Asian units?
Yes, the Chi is the historical basis for similar traditional length units in neighboring countries, which evolved independently over time:
- Japan: Shaku (尺) - Modern standardized value is 10/33 meters (approx. 30.3 cm).
- Korea: Cheok (척) or Ja (자) - Modern standardized value is also 10/33 meters (approx. 30.3 cm).
- Vietnam: Thước - Various historical values, sometimes aligned with Chinese standards.
Is the Chi an SI unit?
No, the Chi is not an SI unit. It is a traditional Chinese unit. The SI base unit for length is the meter (m).
Is the Chi still used today?
Officially, China uses the metric system (SI units) for all legal, commercial, and scientific purposes. However, the Chi (and its subdivision, the Cun) still sees use in:
- Traditional crafts and arts.
- Traditional Chinese Medicine (TCM) for body measurements.
- Cultural and historical contexts.
- Informal measurements in some communities.
- The term "Chi" might sometimes be used colloquially to refer to 1/3 of a meter.
Where does the name 'Chi' and the character 尺 come from?
The character 尺 is a pictogram. Its earliest forms are thought to depict a hand stretching out or a measuring tool. Its exact etymological origin related to a specific body part is debated, but it has represented this fundamental unit of length for millennia.
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.
