About the arpent
The arpent is both a length and an area. As a length, the North American arpent is 180 French feet, officially 191.835 English feet in Canada. A square arpent of area is therefore about 36,800.67 sq ft, or 0.845 acre. French settlers laid out long, narrow lots along the St. Lawrence and the Mississippi, so old descriptions often give frontage in linear arpents and depth in arpents too.
US states that inherited French land grants fixed slightly different legal values: 0.84628 acre in Louisiana, Mississippi, Alabama and Florida, and 0.8507 acre in Arkansas and Missouri. Mauritius and Seychelles use a larger arpent of about 4,220.87 m² (about 1.04 acres).
Values vary by place, so use the definition of the jurisdiction where the land lies, and rely on the recorded survey for a specific parcel.
