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 ...
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.

Therefore, the Melbourne Cup was changed from 2 mi to 3,200 m, a reduction of 19 m or about 0.6%. The first metric Melbourne Cup was raced in November ...
In Puerto Rico, a cuerda is a traditional unit of land area nearly equivalent to 3,930 square meters, or 4,700 square yards, 0.971 acre, or 0.393 hectare (ha). The precise conversion is 1 cuerda = 3,930.395625 m 2. The term "Spanish acre" instead has been used sometimes by mainlanders.
