What is a Toise and a Yojana?
The Toise is an historical French unit of length, used extensively before the adoption of the metric system. It was legally defined as 6 pieds du roi (French royal feet).
Based on the standard established for the pied du roi, the Toise equates to:
- Exactly 1.94903631 meters (m) (based on the 1799 definition of the meter relative to the standard Toise bar)
- Approximately 6.395 English feet (ft)
- Approximately 76.73 English inches (in)
The Toise was further subdivided:
- 1 Toise = 6 Pieds (French feet)
- 1 Toise = 72 Pouces (French inches)
- 1 Toise = 864 Lignes (French lines)
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 Toise 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 Toise and Yojana
The Toise was a fundamental unit of length in France for centuries, used in various fields from the Middle Ages through the Ancien Régime and into the early post-revolutionary period. Its name derives from the Latin tensa, meaning "stretched (arms)", suggesting an origin related to fathom.
Standardization was crucial. The primary standard became the Toise du Châtelet, an iron bar embedded in the wall of the Grand Châtelet fortress in Paris. In 1668, this standard was physically copied by Jean Picard and used for geodetic surveys. Later, a copy known as the Toise du Pérou (or Toise de l'Académie) became the official reference standard for French length measurements. This specific bar was physically used in the famous French Geodesic Missions to Peru (1735–1744) and Lapland (1736–1737), which aimed to measure the length of a degree of latitude near the equator and the Arctic Circle, respectively.
These measurements, based on the Toise, were instrumental in determining the shape of the Earth and ultimately provided the basis for the definition of the meter. The meter was initially defined in the 1790s as one ten-millionth of the distance from the North Pole to the Equator along the meridian passing through Paris, a distance calculated from the geodetic surveys performed using the Toise standard.
The Toise was officially replaced by the meter following the French Revolution and the establishment of the metric system in France, formally adopted in 1799.
- 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 toise and yojanas
Explore the typical applications for both Toise (imperial/US) and Yojana (imperial/US) to understand their common contexts.
Common Uses for toise
The Toise is now obsolete but was historically essential for:
- Land Surveying: Measuring land areas, property boundaries, and distances for cartography.
- Architecture and Civil Engineering: Designing and constructing buildings, bridges, canals, roads, and fortifications (notably by Vauban). Dimensions of major historical French structures were often specified in Toise.
- Military Engineering: Laying out fortifications, measuring artillery ranges.
- Geodesy and Scientific Measurement: Serving as the standard unit for precise scientific measurements, particularly in astronomy and the crucial 18th-century geodetic surveys that measured the Earth.
- Craftsmanship: Used in various trades requiring length measurements.
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 Toise (toise)
How long is a Toise?
The standard French Toise is defined as 6 pieds du roi (French royal feet). This corresponds to:
- Exactly 1.94903631 meters
- Approximately 6.395 English feet
How does the Toise compare to a Meter?
- 1 Toise ≈ 1.949 meters
- 1 Meter ≈ 0.513 Toise The Toise was the historical standard upon which the original definition of the meter was based through geodetic surveys.
What were the subdivisions of the Toise?
The Toise was divided based on the French foot (pied du roi):
- 1 Toise = 6 Pieds
- 1 Pied = 12 Pouces (inches)
- 1 Pouce = 12 Lignes (lines) Therefore, 1 Toise = 72 pouces = 864 lignes.
Is the Toise an SI unit?
No, the Toise is not an SI unit. It is a traditional unit from the pre-metric French system (Mesures usuelles). The SI base unit for length is the meter (m).
Is the Toise still used today?
No, the Toise is obsolete and not used in modern measurements. It was legally replaced by the meter in France and elsewhere. Its significance today is purely historical, particularly in the context of historical architecture, engineering, surveying, and the scientific history leading to the metric system.
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).
