A Bolt is a commercial unit of length primarily used for measuring rolls of cloth or fabric. Unlike standardized units like the meter or yard, the length of a bolt is not fixed and can vary significantly depending on the type of material, the manufacturer, the country of origin, and trade customs.
Common lengths often associated with a bolt include:
- 40 yards (approximately 36.58 meters) - Frequently cited, especially for cottons and silks in the US.
- 100 yards (approximately 91.44 meters) - Often used for heavier fabrics like canvas.
- Other lengths such as 30, 50, 60, or 120 yards may also be encountered.
The bolt represents a quantity convenient for wholesale trade, manufacturing, and inventory management rather than a precise scientific measurement.
The Link, specifically Gunter's Link (symbol li), is a unit of length historically used in surveying, particularly within the imperial and U.S. customary systems. It is defined as exactly 1/100th of a Gunter's chain.
One Gunter's link is equivalent to:
- 0.01 Gunter's chains
- 7.92 inches (in)
- 0.66 feet (ft) (exactly 2/3 of a foot)
- 0.22 yards (yd)
- 0.04 rods (also called poles or perches)
- 0.201168 meters (m) (exactly)
- 20.1168 centimeters (cm)
A Gunter's chain itself measures 66 feet, 22 yards, 4 rods, or 20.1168 meters.
Note: The Bolt is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Link (Gunter's) belongs to the imperial/US customary system.
History of the Bolt and Link (Gunter's)
The concept of the bolt emerged from the practical needs of the textile industry. As cloth production scaled up, manufacturers and merchants needed a standardized way to handle, store, and trade large quantities of fabric. Winding cloth onto a roll or board (the "bolt") provided a convenient package.
The length associated with a bolt likely developed through trade customs specific to different types of fabric and regions. There was never a universal legal standard defining its length, leading to the wide variations seen historically and currently. While retail sales shifted towards measurement by the yard or meter, the bolt remained a useful unit in wholesale and industrial contexts. Even with the global adoption of the metric system, the term "bolt" persists in the textile trade as a reference to a full roll of fabric, though the exact length is usually specified separately in yards or meters.
The link, as part of Gunter's chain, was devised by the English clergyman and mathematician Edmund Gunter around 1620. He introduced a measuring chain that was 66 feet long and divided into 100 links. This system was revolutionary for surveyors because its decimal nature (100 links per chain) simplified calculations, especially for area. Land area could be easily calculated in square chains and then converted to acres, as 10 square chains equal exactly 1 acre. Gunter's chain and its links became the standard tools for land surveying in England and later throughout the British Empire and the United States for centuries.
Common Uses and Applications: bolts vs links
Explore the typical applications for both Bolt (imperial/US) and Link (Gunter's) (imperial/US) to understand their common contexts.
Common Uses for bolts
The bolt is almost exclusively used within the textile industry:
- Wholesale Trade: Fabric manufacturers sell cloth to distributors or large buyers in bolts.
- Manufacturing: Clothing and upholstery manufacturers purchase fabric by the bolt for production runs.
- Inventory Management: Textile mills, warehouses, and large retailers manage stock using bolts as units.
- Industrial Fabrics: Suppliers of canvas, vinyl, and other industrial textiles often sell material by the bolt.
It is generally not used for retail sales to consumers, where fabric is typically measured and cut to specific lengths (yards or meters) from the bolt.
When to Use links
The Gunter's link is now largely obsolete but was historically significant:
- Land Surveying: It was the fundamental unit for measuring property boundaries and land parcels in English-speaking countries for over 300 years.
- Cartography: Used in creating maps and plats based on surveys.
- Land Records: Measurements in links (and chains) frequently appear in older property deeds, historical surveys, and legal descriptions of land. Understanding the link is crucial for interpreting these documents.
- Agriculture: The system was tied to the definition of the acre, a common unit of land area.
Its use declined dramatically with the adoption of the metric system and the advent of more precise surveying technologies like steel tapes, theodolites, Electronic Distance Measurement (EDM), and GPS.
Additional Unit Information
About Bolt (bolt)
How long is a bolt of cloth?
There is no single standard length. It depends heavily on the fabric type and manufacturer. Common lengths include:
- 40 yards (~36.58 m)
- 100 yards (~91.44 m)
- Other lengths like 30, 50, 60, or 120 yards are also possible. Always check the specific product information for the actual length of a particular bolt.
How many yards are in a bolt?
Commonly 40 yards or 100 yards, but this is highly variable.
How many meters are in a bolt?
Based on common yard lengths:
- A 40-yard bolt is approximately 36.58 meters.
- A 100-yard bolt is approximately 91.44 meters.
Is the bolt a standardized unit?
No, it is not a standardized unit of length like the yard or meter. It's a commercial trade unit whose length varies.
Is the bolt still used today?
Yes, the term "bolt" is still widely used in the wholesale textile industry and manufacturing contexts to refer to a full roll of fabric, although the precise length is usually specified in yards or meters.
Is this related to the fastener "bolt"?
No, the bolt unit for cloth is completely unrelated to the metal fastener known as a bolt. They share the same name but have entirely different meanings and origins.
About Link (Gunter's) (li)
How long is a Gunter's Link?
One Gunter's Link is equal to:
- 7.92 inches
- 0.66 feet (2/3 ft)
- 0.201168 meters
- 20.1168 centimeters
How many links are in a Gunter's chain?
There are exactly 100 links in one Gunter's chain.
How long is a Gunter's Chain?
One Gunter's chain is equal to:
- 100 links
- 66 feet
- 22 yards
- 4 rods (or poles, perches)
- 1/10th of a furlong
- 1/80th of a statute mile
- 20.1168 meters
How does the link relate to the acre?
The link is directly related to the acre through the Gunter's chain. An acre is defined as 10 square chains. Since 1 chain = 100 links:
- 1 acre = 10 × (100 links)² = 10 × 10,000 square links = 100,000 square links. This decimal relationship greatly simplified area calculations for surveyors using the chain.
Is the link an SI unit?
No, the Gunter's link is not an SI unit. It is part of the traditional imperial and U.S. customary systems. The corresponding SI unit for length is the meter (m).
Is the Gunter's link still used today?
No, the Gunter's link is rarely used in modern surveying practice. Its primary relevance today is in historical contexts, particularly when interpreting old land deeds, surveys, and maps created using Gunter's system. Modern surveying relies on meters or feet, measured with advanced electronic equipment.
Why was it called a 'link'?
It was called a 'link' because Gunter's chain was literally constructed from 100 physical metal links connected by rings. Each link served as a unit of measurement.
