In Haiti, 19ᵗʰ – 21^stcenturies, a unit of land area, approximately 1.29 hectares (approximately 3.19 acres)¹.

In colonial times it is said to have been the area of a square 100 pas on a side.² The source states that in Saint-Domingue (what would become Haiti) the pas was 3½ pieds, while in other French colonies, such as Guadaloupe or Cayenne, the pas was only 3 pieds. This is somewhat strange, as in France, according to Doursther, the pas was 2½ pieds (the geometric pas was 5 pieds).

A square 350 pied on a side would have an area of 12,926.32 square meters, which fits the 20ᵗʰ century value pretty well; a square 300 pied on a side would have an area of 9496.90 square meters.
