What is a Rope and a Sajene?
The Rope is an historical English unit of length, primarily used in surveying and sometimes in building or architecture. Its length was typically defined as 20 feet.
This equates to:
- 6.096 meters (m)
- Approximately 6.67 yards (yd)
Unlike more standardized surveying units like the chain, the rope's length could sometimes vary by region or specific use, but 20 feet is the most commonly cited value.
The Sajene (Russian: сажень or саже́нь, IPA: [ˈsaʐɨnʲ] or [sɐˈʐɛnʲ]) is an historical Russian unit of length. It was a fundamental unit in the traditional Russian system of measures.
The standard or "state" Sajene (kazyonnaya sazhen) was legally defined as:
- 3 Arshins (another Russian unit)
- 7 English Feet (after Peter the Great's reforms aligned some Russian units with English standards)
- 84 English Inches
This equates to:
- Exactly 2.1336 meters (m)
- Exactly 7 feet (ft)
- Exactly 84 inches (in)
The Sajene was subdivided as follows:
- 1 Sajene = 3 Arshins
- 1 Arshin = 16 Vershoks (meaning 1 Sajene = 48 Vershoks)
Note: The Rope is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Sajene belongs to the imperial/US customary system.
History of the Rope and Sajene
The origin of the Rope unit likely stems directly from the use of actual ropes of a predetermined length for measuring land or distances in medieval England and potentially earlier. Before the widespread adoption of more durable and precise measuring tools like metal chains (such as Gunter's chain, introduced in the 17th century), knotted or marked ropes served as practical, albeit less accurate, instruments for surveyors.
The length of 20 feet provided a convenient measure for certain types of land division or construction layout. However, ropes were susceptible to stretching, shrinking (when wet), and wear, leading to inconsistencies. This lack of precision contributed to its gradual replacement by the rod (16.5 feet) and the chain (66 feet) for official surveying work. The Rope unit fell into obsolescence as measurement standards became more rigorous and legally defined.
The Sajene was used in Russia for centuries, likely originating from an anthropomorphic measurement related to the span of outstretched arms or a person's reach, similar to the fathom in other systems. The name itself may derive from Slavic roots related to reaching or stretching.
While informal variations existed, the unit was standardized over time, notably under Peter the Great (reigned 1682–1725), who aligned the Arshin with 28 English inches, thereby fixing the standard Sajene at exactly 7 English feet (2.1336 m).
The Sajene remained a primary unit for larger measurements in Russia until the metric system was adopted following the Russian Revolution. The metric system became compulsory in the USSR on January 1, 1925, rendering the Sajene and other traditional units obsolete for official use.
Common Uses for ropes and sajenes
Explore the typical applications for both Rope (imperial/US) and Sajene (imperial/US) to understand their common contexts.
Common Uses for ropes
The Rope is now an obsolete unit, but historically it was used for:
- Land Surveying: Measuring property boundaries, fields, and plots of land, particularly in older or less formal surveys.
- Building and Construction: Laying out foundations or measuring lengths in large-scale construction projects in historical contexts.
- Agriculture: Estimating field sizes or row lengths.
- Nautical Measurement (Less Common): Occasionally, "rope" might refer to specific lengths used on ships, but this is distinct from the land surveying unit and often context-dependent (similar to a "cable length").
Common Uses for sajenes
The Sajene is now obsolete but was historically essential in various fields in Russia:
- Land Surveying: Measuring land plots, distances, and property boundaries.
- Architecture and Construction: Specifying dimensions of buildings, structures, and materials like timber.
- Shipbuilding: Measuring lengths related to ship design and construction.
- Rope Making: Measuring lengths of rope.
- Cartography: Used in mapmaking and geographical measurements.
- Folk Measurement: Appeared in everyday language and descriptions of distance or height.
Frequently Asked Questions
Questions About Rope (rope)
How long is a Rope?
The most common definition for the historical English Rope unit is 20 feet, which is exactly 6.096 meters.
How does the Rope compare to other surveying units?
- Rod (or Pole, Perch): 1 Rod = 16.5 feet. Therefore, 1 Rope ≈ 1.21 Rods.
- Gunter's Chain: 1 Chain = 66 feet = 4 Rods. Therefore, 1 Chain = 3.3 Ropes.
- Foot: 1 Rope = 20 feet.
- Yard: 1 Rope ≈ 6.67 yards.
Was the Rope a standardized unit?
No, it was not rigorously standardized like later units such as the foot or the Gunter's chain. While 20 feet was a common value, variations could exist, and the physical nature of a rope made it inherently less precise than metal instruments.
Is the Rope unit still used today?
No, the Rope as a formal unit of length is obsolete. Modern surveying uses meters, feet, and occasionally chains or rods in specific legal contexts (like older land deeds in the US), but not the Rope.
Is the Rope an SI unit?
No, the Rope is not an SI unit. It is a traditional English unit. The SI base unit for length is the meter (m).
About Sajene (sajene)
How long is a Sajene?
The standard Russian Sajene (kazyonnaya sazhen) is exactly:
- 2.1336 meters
- 7 English feet
- 84 English inches
- 3 Arshins
What were the subdivisions of the Sajene?
The Sajene was divided into smaller traditional Russian units:
- 1 Sajene = 3 Arshins
- 1 Arshin = 16 Vershoks
- Therefore, 1 Sajene = 48 Vershoks.
Were there different types of Sajene?
Yes, besides the standard "state" Sajene (7 feet), two other common variations based on body measurements existed historically, though their lengths were less standardized:
- Makhovaya Sajene (Маховая сажень - "swinging" or "sweeping" Sajene): The distance between the fingertips of a person's outstretched arms, roughly equivalent to a fathom (approx. 1.76 meters or 5.77 feet).
- Kosaya Sajene (Косая сажень - "oblique" Sajene): The distance from the toes of one foot to the fingertips of the opposite arm raised diagonally upwards (approx. 2.48 meters or 8.14 feet). This was often used idiomatically to describe someone tall and broad-shouldered.
The kazyonnaya sazhen (7 feet) was the official standard used for legal and technical purposes.
How does the Sajene compare to a Meter or Fathom?
- 1 Sajene = 2.1336 meters
- 1 Meter ≈ 0.4687 Sajenes
- The standard Sajene (2.1336 m / 7 ft) is slightly longer than the standard English fathom (1.8288 m / 6 ft). The Makhovaya Sajene (~1.76 m) was closer in concept and length to the fathom.
Is the Sajene an SI unit?
No, the Sajene 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).
Is the Sajene still used today?
No, the Sajene is obsolete and not used in modern measurements in Russia or elsewhere. It was officially replaced by the metric system in 1925. Its significance today is purely historical, found in old texts, documents, literature, and descriptions of historical sites or objects.
