What is a Cable Length and a Versta?
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 Versta (Russian: верста́, plural: вёрсты, vyorsty) is an obsolete Russian unit of length or distance. It was defined as being equal to 500 sazhenes (саже́нь).
Based on the standardized sajene of 7 English feet (2.1336 meters) established under Peter the Great, one Versta is equal to:
- 1066.8 meters (m)
- 1.0668 kilometers (km)
- Approximately 3500 feet (ft)
- Approximately 0.6629 miles (mi)
Note: The Cable Length is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Versta belongs to the imperial/US customary system.
History of the Cable Length and Versta
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".
The Versta was a traditional unit of distance in Russia, used since at least the 11th century. Its length varied historically until Peter the Great standardized the Russian system of measures in the 18th century, linking the sajene to the English foot (1 sajene = 7 feet). This fixed the Versta at 500 * 7 = 3500 feet, or 1066.8 meters.
- Imperial Russia: The Versta became the standard unit for measuring road distances throughout the Russian Empire. Roads were often marked with verst posts (верстово́й столб, verstovoy stolb) indicating distances.
- Mezhevaya Versta: A less common "boundary versta" (межева́я верста́, mezhevaya versta) also existed, primarily for land surveying. It was twice as long, equal to 1000 sazhenes (approximately 2.13 km). Unless specified otherwise, "Versta" usually refers to the standard 500-sajene unit.
- Metrication: The Versta became obsolete after the Russian Revolution. The metric system was officially adopted in 1918 and became mandatory in 1925, replacing the traditional Russian units.
Common Uses for cable lengths and versts
Explore the typical applications for both Cable Length (imperial/US) and Versta (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 versts
The Versta was primarily used for:
- Measuring Travel Distances: It was the standard unit for road distances between towns and cities in Imperial Russia. Maps, travel guides, and road markers all used Versts.
- Postal System: Distances for mail delivery and stagecoach routes were measured in Versts.
- Literature: The Versta frequently appears in Russian literature of the 18th and 19th centuries (e.g., works by Pushkin, Gogol, Tolstoy, Chekhov) to describe journeys and distances, adding historical context.
- Military: Used for measuring marching distances and geographical surveys.
Its use today is purely historical or literary.
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 Versta (versta)
How long is a Versta?
A standard Versta is exactly:
- 1066.8 meters
- 1.0668 kilometers
- Approximately 0.6629 miles
- Approximately 3500 feet
- Exactly 500 sazhenes
What were the main related Russian units?
The Versta was part of the Imperial Russian system of measures:
- 1 Versta = 500 Sajenes (саже́нь)
- 1 Sajene = 3 Arshins (арши́н) ≈ 2.13 m / 7 ft
- 1 Arshin = 16 Vershoks (вершо́к) ≈ 71.1 cm / 28 in
- 1 Vershok ≈ 4.445 cm / 1.75 in
Was there more than one type of Versta?
Yes, besides the standard "travel" Versta (500 sazhenes), there was a Mezhevaya Versta ("boundary versta") used for land surveying, which was equal to 1000 sazhenes (about 2.13 km). The 500-sajene Versta was far more common.
Is the Versta still used today?
No, the Versta is obsolete. It was officially replaced by the kilometer and meter when Russia adopted the metric system in the early 20th century (mandatory from 1925). Its use is now confined to historical contexts and literature.
How does a Versta compare to a kilometer or a mile?
- A Versta is slightly longer than a kilometer: 1 Versta ≈ 1.07 km.
- A Versta is significantly shorter than a mile: 1 Versta ≈ 0.66 miles (roughly two-thirds of a mile). Conversely, 1 mile ≈ 1.51 Versts.
Is the Versta an SI unit?
No, the Versta is not an SI unit. It is a traditional unit from the historical Russian system of measurement. The SI base unit for length is the meter (m).
