Units explained
Arpent (Canadian)
A Canadian arpent is a historical unit of area equal to exactly 3418.89 m². Used in French-Canadian land records, especially in Quebec and Louisiana.
Standardized in French colonial Canada at 100 perches squared, the perche being the Canadian standard of 18 French pieds.
Canadian arpents appear in legal land descriptions in Quebec, where they remain officially recognized for historical seigneurial properties. Also appear in Louisiana land records from the French colonial period.
French colonial Canadian/Louisiana origin; remains in legal use in Quebec for historical properties.
Hectare
A hectare is a metric unit of area equal to 10,000 square meters, or one square hectometer. It is the most widely used metric unit for land measurement worldwide.
Defined as 100 ares, equal to one square hectometer. The name was introduced in 1795 in France as part of the metric system.
Hectares are the standard unit for agricultural land measurement worldwide except in the US (which uses acres). 1 hectare equals 2.47105 acres. In India, hectares are used in modern agricultural census and land records alongside traditional regional units.
Adopted in France in 1795; standardized internationally through the SI system.
