A French arpent is a historical unit of land area used in pre-metric France, approximately 4221 m² (close to one acre).
Originated as a medieval French land unit; varied considerably by province. The 'arpent de Paris' was officially fixed at 100 perches squared, the perche being 18 pieds.
French arpents appear in pre-revolutionary French land records and in genealogical research. The unit was largely abolished after the French Revolution in favor of metric units.

Pyeong
A pyeong is a Korean unit of area equal to approximately 3.3058 m² (about 35.58 square feet).
Originated as a traditional East Asian land unit. Korean usage standardizes pyeong at 400/121 m² ≈ 3.3058 m². Defined as the area of a 6-by-6 Korean foot (cheok) square.
Pyeong is the primary unit for residential real estate in South Korea. Although the government tried to phase pyeong out in favor of square meters from 2007, the unit remains in widespread popular use, particularly for apartment sizes.
Traditional East Asian unit; remains in widespread Korean use despite government metric campaigns.
