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 ...
For example, the NIST document has 1 square mile = 2.589 988 E+06 square meters. The convert template has 1 square mile = 2,589,988.110336 square meters. Values for the fundamental physical constants come from the NIST Reference on Constants, Units, and Uncertainty , either the 2010 or the 2014 version.
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.

The Byzantine or Morean stremma continued to vary depending on the period and the quality of the land, but usually enclosed an area between 900–1,900 m 2 (9,700–20,500 sq ft). [2] It was originally also known as the "plethron" but this was eventually replaced by "stremma", derived from the verb for "turning" the ground with a Byzantine plow.
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.
