The hectare (/ ˈ h ɛ k t ɛər,-t ɑːr /; SI symbol: ha) is a non-SI metric unit of area equal to a square with 100-metre sides (1 hm 2), that is, 10,000 square metres (10,000 m 2), and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about 0.405 hectares and one hectare contains about ...
One acre equals 1 ⁄ 640 (0.0015625) square mile, 4,840 square yards, 43,560 square feet, [2] or about 4,047 square metres (0.4047 hectares) (see below).While all modern variants of the acre contain 4,840 square yards, there are alternative definitions of a yard, so the exact size of an acre depends upon the particular yard on which it is based.
Hence each Katha is 2,880 square feet (268 m 2) in area, although this may vary within different regions of Assam. 4 bighas together are further termed as a Pura. 1 Katha = 2,880 square feet (268 m 2) or 320 sq yard; 1 Lessa = 144 square feet (13.4 m 2) or 16 sq yard; 1 Acre = 3.025 bigha and 1 Hectare = 7.475 bigha (Assam)
On average, a global hectare can be produced in the area of a standard hectare. A hectare (/ ˈ h ɛ k t ɛər /; symbol ha) is a unit of area equal to 10,000 square metres (107,639 sq ft) (a square 100 metres on each side or 328 feet on each side), 2.471 acres, 0.01 square kilometers, 0.00386102 square miles, or one square hectometre (100 metres squared).
The unit is still in use in many areas previously ruled by the Ottomans, although the new or metric dunam has been redefined as exactly one decare (1,000 square metres (11,000 sq ft)), which is 1/10 hectare (1/10 × 10,000 square metres (110,000 sq ft)), like the modern Greek royal stremma. [3]
[1] [2] In Afghanistan, however, it is standardized at 2,000 square metres (0.49 acres). [ 2 ] [ 3 ] The jerib was roughly equivalent to the other customary land measures in south Asia and the Middle East, the Indian bigha and the Sumerian iku , varying between 1,600 and 3,600 square metres (0.40 and 0.89 acres).
