The decimeter (symbol: dm) is a unit of length in the metric system. It is defined as exactly one-tenth (1/10) of a meter, which is the base unit of length in the International System of Units (SI). Therefore, 1 meter equals 10 decimeters.
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 Decimeter is part of the metric (SI) system, primarily used globally in science and trade. The Arpent belongs to the imperial/US customary system.
History of the Decimeter and Arpent
The decimeter originates from the French Revolution era, when the metric system was developed and introduced in France in the 1790s. The system aimed to create a rational and universal standard of measurement based on decimal multiples and submultiples of base units. The prefix "deci-" signifies a factor of one-tenth (10β»ΒΉ). While the meter became the standard, the decimeter was defined as a convenient subdivision.
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: decimeters vs arpents
Explore the typical applications for both Decimeter (metric) and Arpent (imperial/US) to understand their common contexts.
Common Uses for decimeters
Although less frequently used in everyday measurements compared to the meter, centimeter, or millimeter, the decimeter finds application in certain contexts:
- Education: Often used in schools to teach the metric system and decimal relationships (10 dm = 1 m, 1 dm = 10 cm).
- Crafts and Sewing: Sometimes used for measuring fabric or materials where increments of 10 centimeters are practical.
- Scientific Fields: Occasionally used in specific scientific measurements or contexts where this scale is convenient.
- Volume: The cubic decimeter (dmΒ³) is a very common unit of volume, as it is exactly equal to one liter (L). This link makes the decimeter conceptually important in understanding metric volume.
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 Decimeter (dm)
How many decimeters are in a meter?
There are exactly 10 decimeters in 1 meter.
How many centimeters are in a decimeter?
There are exactly 10 centimeters in 1 decimeter.
How many millimeters are in a decimeter?
There are exactly 100 millimeters in 1 decimeter (since 1 dm = 10 cm and 1 cm = 10 mm).
How do you convert decimeters to inches?
To convert decimeters to inches, multiply the number of decimeters by approximately 3.93701. For example, 2 dm is about 2 * 3.93701 = 7.874 inches.
Is the decimeter commonly used?
The decimeter is not as commonly used in everyday language or general measurements as meters, centimeters, or even millimeters. However, it is a standard metric unit and is particularly important conceptually due to the cubic decimeter being equal to a liter.
What is a cubic decimeter?
A cubic decimeter (dmΒ³) is a unit of volume equal to the volume of a cube with sides one decimeter (10 cm) long. It is exactly equivalent to 1 liter (L).
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).
