The Finger (sometimes finger's breadth, though this can be confusingly similar to the 'digit') is an archaic English unit of length. Its definition was inconsistent, leading to significant ambiguity. Two primary definitions existed:
-
As 1/8th of a yard: This was a common definition, equating the finger to:
- 4.5 inches (in)
- 1/2 of a quarter-yard (or "quarter")
- 0.1143 meters (m)
- 11.43 centimeters (cm)
-
As 1/16th of a yard: This definition made the finger identical to another unit called the nail, equating it to:
- 2.25 inches (in)
- 0.05715 meters (m)
- 5.715 centimeters (cm)
The term likely originated from anthropomorphic measurement but became tied to fractions of the standard yard, particularly in the context of measuring cloth. It is distinct from, and generally longer than, the unit called a digit (typically ~0.75 inches).
The Arpent is a historical French unit used primarily for measuring land area, but also sometimes used as a unit of length. As a unit of length, the arpent typically referred to the side length of a square arpent of land.
Its precise length varied significantly by region and time period in France and its colonies. A commonly cited value, particularly associated with the arpent de Paris, is based on 180 French feet (pieds du Roi), which equates to approximately:
- 58.47 meters (m)
- 191.8 feet (ft)
Other variations existed, such as the arpent commun (based on 200 French feet, ~64.97 m) and the arpent d'ordonnance (based on 220 French feet, ~71.47 m).
Note: The Finger is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Arpent belongs to the imperial/US customary system.
History of the Finger and Arpent
The finger was used historically in England, primarily from the medieval period into the early modern era. Its main application was in the measurement of cloth, alongside other specialized units like the nail (often 2.25 inches) and the ell (often 45 inches).
The existence of multiple definitions (4.5 inches vs. 2.25 inches) highlights the lack of strict standardization for many older units. The 2.25-inch finger was identical to the nail, suggesting the terms might have been used interchangeably in some contexts or that one definition arose from confusion with the other.
Compared to more fundamental units like the inch, foot, yard, or even the digit and palm, the "finger" as a distinct unit (especially the 4.5-inch version) appears less frequently in historical records. Its usage declined significantly with the standardization of the Imperial system (which favored inches and yards) and the later adoption of the metric system. It is now entirely obsolete.
The term "arpent" likely derives from the Gaulish arepennis, meaning "end of a field," suggesting its origins relate to agricultural land measurement, possibly representing the amount of land that could be plowed in a day. It became a fundamental unit for land surveying in France during the medieval period and remained in use until the adoption of the metric system following the French Revolution.
- Regional Variations: Before standardization efforts, the length (and thus area) of the arpent varied considerably across different regions of France. Key variations included:
- Arpent de Paris: Based on a perche (rod) of 18 pieds du Roi (French feet), with the linear arpent (side of the square) being 10 perches, totaling 180 pieds (~58.47 m). The area was 32,400 square pieds.
- Arpent Commun: Based on a perche of 20 pieds, linear arpent of 200 pieds (~64.97 m). Area: 40,000 square pieds.
- Arpent d'Ordonnance (or Arpent des Eaux et ForΓͺts): Based on a perche of 22 pieds, linear arpent of 220 pieds (~71.47 m). Area: 48,400 square pieds. Used primarily for royal forests.
- Colonial Usage: The arpent was exported to French colonies, notably:
- New France (Quebec, Canada): The arpent de Paris became the standard for land grants along the St. Lawrence River, shaping the characteristic long, narrow farm plots (rangs).
- Louisiana (USA): The French arpent (usually the arpent de Paris) was used for land measurement before and sometimes after the Louisiana Purchase. Its legacy persists in land titles and some place names.
- Metrication: The metric system officially replaced the arpent and other traditional units in France in the late 18th and early 19th centuries, though its use lingered in practice and historical records.
Common Uses and Applications: fingers vs arpents
Explore the typical applications for both Finger (imperial/US) and Arpent (imperial/US) to understand their common contexts.
Common Uses for fingers
The finger is obsolete and has no modern practical application. Its relevance is primarily historical:
- Historical Cloth Trade: Measurements in "fingers" might be encountered in older English documents, inventories, or tailor's records related to textiles. Understanding its potential ambiguity (4.5 vs 2.25 inches) is crucial.
- Understanding Historical Units: Studying the finger helps illustrate the complexity and variability of pre-standardized measurement systems and the specific units used in the textile industry.
- Rare & Obsolete: It was never as widespread or consistently defined as units like the inch, foot, or yard.
When to Use arpents
The Arpent (both linear and area) is now largely obsolete for practical measurement but remains historically significant:
- Historical Land Surveys: Essential for interpreting old maps, deeds, and land grants in France, Quebec, Louisiana, and other areas formerly under French control (e.g., parts of the US Midwest like Missouri, Illinois, Indiana).
- Legal Context: Land descriptions in some regions may still reference original measurements in arpents, requiring conversion for modern understanding.
- Historical Research: Understanding the arpent is crucial for historians studying agriculture, settlement patterns, and land tenure systems in French history and its colonial contexts.
- Unit of Area: While this page focuses on the length, the arpent is more commonly known and encountered as a unit of area (the square arpent).
Additional Unit Information
About Finger (finger)
How long is a Finger?
The length of a finger was not consistently defined. The two most common historical definitions in England were:
- 4.5 inches (11.43 cm), equal to 1/8th of a yard.
- 2.25 inches (5.715 cm), equal to 1/16th of a yard (and identical to the unit called a 'nail'). Context is essential when encountering this unit in historical texts.
Is a Finger the same as a Digit?
No. Although both terms relate to the human finger, they represented different historical units of length.
- The Digit (or fingerbreadth) was typically much shorter, around 0.75 inches (approx. 1.9 cm), representing the width of a finger.
- The Finger was significantly longer, either 4.5 inches or 2.25 inches, likely derived as a fraction of a yard rather than directly from finger anatomy in later usage.
What is the relationship between a Finger and a Nail?
The unit called a Nail was commonly defined as 1/16th of a yard (2.25 inches). Therefore:
- One definition of the Finger (2.25 inches) was identical to the Nail.
- The other common definition of the Finger (4.5 inches) was twice the length of a Nail.
Is the Finger an SI unit?
No, the finger is not an SI unit. It is an archaic, non-standardized unit primarily used historically in England. The SI base unit for length is the meter (m).
Is the Finger still used?
No, the finger as a unit of length is completely obsolete and is not used in any modern standard, scientific, or commercial measurements. Its relevance is purely historical.
Where does the name 'Finger' come from?
The name undoubtedly originates from the human finger. However, while the digit unit directly related to finger width, the 'Finger' unit (especially the 4.5-inch version) seems to have become a conventional term for a specific fraction (1/8th or 1/16th) of a yard, particularly in cloth measurement, losing its direct anatomical connection.
About Arpent (arpent)
Is the Arpent a unit of length or area?
The Arpent is primarily known as a unit of area, representing a specific parcel of land. However, a linear arpent also exists, defined as the side length of a square whose area is one arpent. This page focuses on the linear arpent. The relationship is direct: Area Arpent = (Linear Arpent)Β². Because the linear arpent varied, the area also varied.
Where is the Arpent still relevant?
The Arpent is not used for everyday measurements today. Its relevance is almost entirely historical and legal:
- Quebec (Canada): Crucial for understanding historical land division and property lines, especially the seigneurial system.
- Louisiana (USA): Important for interpreting land titles dating back to the French colonial period.
- France: Relevant for historical studies and understanding old documents.
- Other former French territories: May appear in historical records (e.g., Mauritius, parts of the US Midwest).
How long is a linear Arpent?
There is no single value, as it varied regionally. Common historical values include:
- Arpent de Paris: ~180 French feet β 58.47 meters β 191.8 feet (Most common in Quebec & Louisiana)
- Arpent Commun: ~200 French feet β 64.97 meters β 213.2 feet
- Arpent d'Ordonnance: ~220 French feet β 71.47 meters β 234.5 feet (Note: The French foot, pied du Roi, was slightly longer than the English foot, approx. 32.48 cm or 12.79 inches).
How does the linear Arpent compare to a Meter or Foot?
- The most common linear arpent (~58.47 m) is significantly longer than a meter. (1 Arpent β 58.47 m)
- It is also much longer than a foot. (1 Arpent β 191.8 ft)
Is the Arpent an SI unit?
No, the Arpent is not an SI unit. It is a traditional unit from the French system of measurements. The SI base unit for length is the meter (m), and the SI unit for area is the square meter (mΒ²).
