In Afghanistan , ? – 21^{st} century, a unit of area, approximately 1953.6 square meters. The side of a square with an area of 1 jerib is a unit of length, the side of jerib, approximately 44.200 meters.

Returns on these summer crops have improved in recent years, but with total landholdings rarely exceeding five jeribs (around one ha in total), the on-farm income is insufficient to meet the basic needs of households that can frequently have ten members or more.

In Iran , 20ᵗʰ century, two units of area. By the metrication law of 31 May 1926, the metric jerib = 1 hectare (about 2.471 acres). The other is approximately 1,081.6 square meters¹. Also romanized as jarib.

During the Caliphate of `Omar, who bequeathed Arabian `Irāq to
the Moslems, he gave orders to effect its mensuration, and after careful survey
the result showed an area of 36,000,000 Jarībs. Accounting, however, as
beforesaid, that the total area (of the province) is 10,000 square leagues,
since each square league contains 40,000 Jarībs—each Jarīb being a square of 60
ells by 60 ells—these 10,000 square leagues would give 400,000,000 Jarībs. (But
this is in excess, and) the measurement giving 10,000 square leagues can only
be attained on the supposition that the area enclosed by the sides of latitude
and longitude is a right-angled parallelogram.
