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 ...
An area of one square kilometre consists of 100 hectares each containing 10,000 square metres. This page is a progressive and labelled list of the SI area orders of magnitude, with certain examples appended to some list objects.
The unit is still in use in many areas previously ruled by the Ottomans, although the new or metric dunam has been redefined (as of when, by who?) as exactly one decare (1,000 square metres [10,760 square feet]), which is 1/10 hectare (1/10 × 10,000 square metres [107,640 square feet]), like the modern Greek royal stremma.

By default, the output value is rounded to adjust its precision to match that of the input. An input such as 1234 is interpreted as 1234 ± 0.5, while 1200 is interpreted as 1200 ± 50, and the output value is displayed accordingly, taking into account the scale factor used in the conversion.
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.
A Morgen (Mg) is a historical, but still occasionally used, German unit of area used in agriculture. [1] Officially, it is no longer in use, but rather the hectare. [1] While today it is approximately equivalent to the Prussian morgen, measuring 25 ares or 2,500 square meters, its area once ranged from 1,906 to 11,780 square meters, but usually between ¼ and ½ hectare.

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)
