What is a Cable Length and a Yojana?
A Cable Length (symbol cb), often shortened to cable, is a nautical unit of length, traditionally related to the length of a ship's anchor cable. While its exact length has varied historically and geographically, it is now most commonly defined internationally as one-tenth of a nautical mile (1/10 NM).
This standard definition equates to:
- 185.2 meters (m)
- Approximately 607.61 feet (ft)
- Approximately 202.54 yards (yd)
Other historical definitions based on the fathom also exist.
The Yojana (Sanskrit: योजन) is an ancient Indian unit of distance, primarily found in historical texts from South Asia. Its exact length is highly debated and likely varied significantly across different time periods, geographical regions, and textual sources.
There is no single, universally accepted conversion to modern units. Common scholarly estimates place its value anywhere between:
- 8 to 15 kilometers (km)
- Approximately 5 to 9 miles (mi)
Some ancient texts define the Yojana in terms of smaller units, such as:
- 4 krosas (or gorutas)
- 8,000 dhanus ('bows')
- 32,000 hastas ('cubits')
However, the lengths of these base units are also subject to historical variation and interpretation, contributing to the uncertainty surrounding the Yojana.
Note: The Cable Length is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Yojana belongs to the imperial/US customary system.
History of the Cable Length and Yojana
The unit originated from the practical length of a ship's anchor cable (or "shot" of chain) used in the age of sail. Anchor cables were typically manufactured in standard lengths that could be shackled together. This length provided a convenient unit for measuring distances related to anchoring and maneuvering close to shore or other vessels.
However, the length was not universally standardized:
- In the British Royal Navy, a cable was traditionally defined as 100 fathoms (equivalent to 600 feet or 182.88 meters).
- In the U.S. Navy, it was often defined as 120 fathoms (equivalent to 720 feet or 219.456 meters).
With the international adoption of the nautical mile (defined as 1852 meters), defining the cable as exactly one-tenth of this value (185.2 m) created a convenient, decimal-based relationship and became the most common modern standard, sometimes referred to as the "international cable length".
- Ancient Origins: The term "Yojana" appears in some of the oldest Indian literature, including the Vedas, the Puranas, and the great epics like the Ramayana and Mahabharata. It was a standard measure for long distances.
- Buddhist Texts: Buddhist scriptures, such as the Pali Canon, frequently use the Yojana to describe geographical distances, the dimensions of mythical realms, or the extent of a Buddha's journey. Different Buddhist traditions sometimes offer varying interpretations of its length.
- Arthashastra: Kautilya's Arthashastra (an ancient treatise on statecraft, c. 3rd century BCE) provides definitions relating the Yojana to smaller units, suggesting a more standardized system for administrative purposes at that time, though its precise value remains debated.
- Lack of Standardization: Unlike modern systems, ancient Indian measurements were not centrally standardized across the vast subcontinent and over long periods. Local customs, royal decrees, and the specific context (e.g., measuring road distance vs. cosmological scale) could all influence the intended length.
- Interpretations: Modern scholars have attempted to calculate the Yojana based on various methods:
- Analyzing travel times mentioned in texts.
- Comparing described geographical distances with known locations.
- Relating it to astronomical measurements found in cosmological texts.
- Working backward from definitions based on smaller, slightly better-understood units like the hasta (cubit) or angula (finger width). These methods often yield conflicting results.
- Obsolescence: With the advent of standardized systems like the Imperial system during British rule and later the widespread adoption of the metric system, the Yojana fell out of practical use for measurement.
Common Uses for cable lengths and yojanas
Explore the typical applications for both Cable Length (imperial/US) and Yojana (imperial/US) to understand their common contexts.
Common Uses for cable lengths
The cable length, particularly the 1/10 NM definition, remains in use in specific maritime contexts:
- Nautical Navigation & Ship Handling: Measuring short distances at sea, such as the distance between ships in formation, distance off a navigational hazard, distance to a pier, estimating anchor drag, or describing the scope (length) of anchor cable paid out.
- Hydrographic Surveying: Historically used on nautical charts, although meters are now the primary international standard for depth and short distances on modern charts.
- Naval Terminology: Persists in naval traditions and communications for describing close ranges.
- Historical Context: Encountered in older maritime texts, logs, charts, and naval records.
Common Uses for yojanas
The Yojana is primarily encountered today in:
- Historical Studies: Understanding ancient Indian geography, trade routes, military campaigns, and administrative divisions described in texts.
- Religious and Literary Studies: Interpreting distances mentioned in Hindu, Buddhist, and Jain scriptures, epics, and classical literature. This includes cosmological descriptions, mythological journeys, and the size of ancient kingdoms or structures.
- Cultural Context: It remains a part of the cultural lexicon in discussions related to ancient Indian heritage and texts.
It is not used for any practical, scientific, or commercial measurements in the modern era.
Frequently Asked Questions
Questions About Cable Length (cb)
What are the different values for a cable length?
The value depends on the definition being used:
- International Standard: 1 cable = 1/10 nautical mile = 185.2 meters ≈ 607.61 feet. (Most common modern definition)
- British Traditional: 1 cable = 100 fathoms = 182.88 meters = 600 feet.
- US Traditional: 1 cable = 120 fathoms = 219.456 meters = 720 feet.
Always clarify which definition is intended if precision is critical, though the 1/10 NM version is generally assumed today unless otherwise specified.
How many meters are in a standard cable length?
The internationally recognized standard cable length is exactly 185.2 meters.
How many feet are in a standard cable length?
The internationally recognized standard cable length is approximately 607.61 feet. The traditional British cable was 600 ft, and the traditional US cable was 720 ft.
Is the cable length related to the nautical mile?
Yes, the most common modern definition establishes a direct relationship: 1 cable length = 1/10 nautical mile.
Is the cable length an SI unit?
No, the cable length is not an SI unit. It is a traditional nautical unit derived from maritime practice and later linked to the nautical mile. The corresponding SI unit for length is the meter (m).
Is the cable length still used today?
Yes, while meters and nautical miles are standard for most navigation, the cable length (especially the 1/10 NM definition) is still actively used in specific maritime applications like anchoring, close maneuvering, naval operations, and sometimes in recreational boating contexts. It serves as a convenient subdivision of the nautical mile.
About Yojana (yojana)
What is the accepted value of a Yojana in modern units?
There is no single universally accepted value. Scholarly estimates vary widely, most commonly falling between 8 kilometers (approx. 5 miles) and 15 kilometers (approx. 9 miles). Some interpretations suggest values as low as 5 km or as high as 20 km. The specific text, time period, and region must be considered.
Why is the length of the Yojana so uncertain?
Several factors contribute to the uncertainty:
- Lack of Central Standardization: Ancient India had diverse local measurement practices.
- Evolution Over Time: The definition likely changed over centuries.
- Variable Base Units: The smaller units (like krosa or hasta) used to define it were also not universally fixed.
- Contextual Differences: The term might have been used differently for road distances, land surveys, or cosmological scales.
- Figurative Use: In some literary or religious contexts, the term might have been used symbolically or hyperbolically rather than as a precise measurement.
How does the Yojana relate to other ancient Indian units?
The Yojana was typically the largest unit in a hierarchical system. A common (though not universal) relationship described in texts like the Arthashastra is:
- 1 Yojana = 4 Krosas (or Gorutas)
- 1 Krosa = 1,000 (or sometimes 2,000) Dhanus (bows)
- 1 Dhanus = 4 Hastas (cubits)
- 1 Hasta = 24 Angulas (finger widths)
The uncertainty in the base units (hasta, angula) contributes to the uncertainty in the Yojana.
Is the Yojana still used today?
No, the Yojana is an obsolete unit of measurement. It has not been used for practical purposes for centuries and has been entirely replaced by the metric system (kilometers, meters) in India and other relevant regions. Its relevance is purely historical, literary, and cultural.
Is the Yojana an SI unit?
No, the Yojana is not an SI unit. It is an ancient, traditional unit of distance from the Indian subcontinent. The SI base unit for length is the meter (m).
