What is a Klafter and a Arpent?
The Klafter is a historical unit of length originating from Central Europe, particularly prominent in German-speaking regions like Austria, Bavaria, Prussia, and Switzerland. It is conceptually similar to the fathom, often defined by the span of a person's outstretched arms.
While its exact length varied significantly by region and time, a widely recognized standard, especially from the Austrian Empire, defines the Klafter as 6 Vienna feet (Wiener Fuß). This equates to approximately:
- 1.8965 meters (m)
- 6.222 feet (ft) (using the Vienna foot of ~0.31608 m)
The Klafter was also used as a unit of area (Quadratklafter or square Klafter) and volume (Kubikklafter or cubic Klafter), especially for measuring firewood (often called a Raummeter or Ster in this context, though volumes could vary). This page focuses on the linear Klafter.
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 Klafter 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 Klafter and Arpent
The term "Klafter" likely derives from Old High German klāftra, related to the act of embracing or grasping, reflecting its origin as an anthropometric unit based on arm span.
- Regional Variations: Before widespread standardization and metrication, the length of the Klafter differed across various German states and Swiss cantons. For example, the Prussian Klafter was slightly different from the Austrian one.
- Standardization Efforts: Attempts were made to standardize measures, with the Austrian system (based on the Wiener Fuß) becoming influential. The definition of 1 Klafter = 6 Fuß (feet) = 72 Zoll (inches) was common, but the length of the Fuß itself varied.
- Dual Use (Length & Volume): The Klafter was notably used for measuring stacked firewood. A Klafter Holz typically referred to a stack of wood 1 Klafter high, 1 Klafter wide, and a specific log length (often 3 or 4 feet), representing a volume unit.
- Metrication: The Klafter became obsolete following the adoption of the metric system across Central Europe, primarily during the latter half of the 19th century (e.g., Germany 1872, Austria 1876).
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 Forêts): 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 for klafter and arpents
Explore the typical applications for both Klafter (imperial/US) and Arpent (imperial/US) to understand their common contexts.
Common Uses for klafter
Historically, the Klafter served various measurement needs:
- Forestry: Measuring timber lengths and, crucially, the volume of stacked firewood.
- Mining: Measuring the depth of shafts and the length of tunnels.
- Construction: Measuring building dimensions, rope lengths, and materials.
- Surveying: Measuring land distances and areas (Quadratklafter), although units like the Ruthe (rod) were also common for land.
- Nautical: Sometimes used similarly to a fathom for measuring water depth or rope lengths, though less common than the English fathom in maritime contexts.
Today, its use is confined to historical records, architectural studies, forestry history, and understanding old land deeds or documents.
Common Uses for 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).
Frequently Asked Questions
Questions About Klafter (klafter)
How long is a Klafter?
The length varied, but the most common standard, based on the Austrian system, is:
- Exactly 6 Vienna Feet (Wiener Fuß)
- Approximately 1.8965 meters
- Approximately 6.222 feet
Other historical values might range roughly from 1.7 to 1.95 meters depending on the specific regional "foot" standard used.
Is a Klafter the same as a fathom?
Conceptually, they are very similar, both derived from the span of outstretched arms. Numerically, they are close but distinct.
- Klafter (Austrian): ~1.8965 meters / ~6.222 feet
- Fathom (International): Exactly 1.8288 meters / 6 feet
So, the common Austrian Klafter was slightly longer than the standard fathom.
What were the main related units in the Austrian system?
The Klafter was part of a system:
- 1 Klafter = 6 Fuß (Vienna Foot or Wiener Schuh)
- 1 Fuß = 12 Zoll (Vienna Inch or Wiener Zoll)
- 1 Zoll ≈ 2.634 cm / 1.037 inches
- 1 Fuß ≈ 31.608 cm / 12.444 inches / 1.037 feet
Where was the Klafter primarily used?
It was used across Central Europe, notably in:
- Austria-Hungary
- Southern German states (Bavaria, Württemberg)
- Prussia (with a slightly different length)
- Switzerland
- Other parts of the Holy Roman Empire and subsequent German Confederation.
Is the Klafter still used today?
No, the Klafter is obsolete for practical measurements. It was replaced by the meter during metrication in the 19th century. Its relevance is purely historical.
How does a Klafter compare to a meter or foot?
- A Klafter (~1.9 m) is almost twice as long as a meter. (1 Klafter ≈ 1.9 m)
- A Klafter (~6.2 ft) is significantly longer than a standard foot. (1 Klafter ≈ 6.2 ft)
Is the Klafter an SI unit?
No, the Klafter is not an SI unit. It is a traditional unit from historical Central European measurement systems. The SI base unit for length is the meter (m).
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)². 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 ≈ 58.47 meters ≈ 191.8 feet (Most common in Quebec & Louisiana)
- Arpent Commun: ~200 French feet ≈ 64.97 meters ≈ 213.2 feet
- Arpent d'Ordonnance: ~220 French feet ≈ 71.47 meters ≈ 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 ≈ 58.47 m)
- It is also much longer than a foot. (1 Arpent ≈ 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 (m²).
