What is a Furlong and a Bolt?
The Furlong (symbol fur) is a unit of length in the imperial and U.S. customary systems of measurement. It is defined as exactly one-eighth of a mile (1/8 mi). This is equivalent to 220 yards (yd), 660 feet (ft), or precisely 201.168 meters (m).
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.
Note: The Furlong is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Bolt belongs to the imperial/US customary system.
History of the Furlong and Bolt
The name "furlong" derives from the Old English words furh (furrow) and lang (long). It originally represented the approximate distance a team of oxen could plow without rest within a typical English open field system. It also related to the traditional size of an acre, which was conceived as an area of land one furlong long and one chain (66 feet) wide. The furlong was standardized as 40 rods (a rod being 5.5 yards) or 10 chains. While historically significant in agriculture and land surveying, its use has greatly diminished with the adoption of metric units and the decline of the imperial system for general measurements.
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.
Common Uses for furlongs and bolts
Explore the typical applications for both Furlong (imperial/US) and Bolt (imperial/US) to understand their common contexts.
Common Uses for furlongs
Although largely obsolete for general use, the furlong persists in specific contexts:
- Horse Racing: Its most prominent modern use is in measuring race distances in countries like the United Kingdom, Ireland, the United States, and Canada. Race lengths are frequently given in furlongs (e.g., a 6-furlong sprint).
- Historical Context: Encountered in historical documents, land deeds, and literature referring to land measurement or travel distances in imperial units.
- Figurative Language: Occasionally used informally or figuratively to denote a distance, though this is rare.
- Myanmar (Burma): The furlong remains in common use in Myanmar as a customary unit alongside the mile.
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.
Frequently Asked Questions
Questions About Furlong (fur)
How many furlongs are in a mile?
There are exactly 8 furlongs in 1 mile.
How many yards/feet/meters are in a furlong?
One furlong is equal to:
- 220 yards (yd)
- 660 feet (ft)
- 201.168 meters (m) (exactly)
Where is the furlong used most often today?
Its primary modern application is in horse racing in several English-speaking countries (UK, Ireland, USA, Canada), where it is the standard unit for race distances. It also sees some continued customary use in Myanmar.
Is the furlong an SI unit?
No, the furlong is not part of the International System of Units (SI). It belongs to the imperial and U.S. customary systems. The corresponding SI unit for length is the meter (m).
Why is it called a furlong?
The name comes from Old English furlang, meaning "furrow long," reflecting its origin as the length of a furrow a team of oxen could plow in an acre strip before needing rest.
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.
