About these units
Arpent (arpent)
The arpent is a French unit of length and area, historically used in France and French colonial territories like Louisiana and Canada. As a length, it was roughly 58.47 meters, while as an area unit it varied regionally but was commonly used for agricultural plots. The arpent was central to land measurement, urban planning, and agriculture, particularly in colonies where standard French units were imposed. It helped define plots for farming, taxation, and property distribution, often in combination with other traditional French units such as the perche. Although largely replaced by metric units, the arpent remains significant for historians, geographers, and legal scholars interpreting colonial-era land documents and property records.
Caliber (cl)
Caliber is a measurement of the internal diameter of a firearm's barrel, typically expressed in fractions of an inch or in millimeters (e.g., 0.45 inches or 9 mm). More broadly, it also refers to the diameter of the ammunition used in that firearm. The evolution of caliber reflects the development of firearms from crude early devices to precisely engineered modern weapons. Early calibers varied wildly, as guns were handmade and ammunition often imprecise. As industrialization progressed, standardization became necessary for safety, compatibility, and mass production. Caliber must be understood in conjunction with factors like barrel length, chamber pressure, rifling, and bullet design. A firearm's caliber alone does not determine its power, but it sets constraints on the types of ammunition and performance profiles possible. As both a technical and regulatory term, caliber remains central to engineering, law enforcement, and military logistics.
