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 ...
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).
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.
For example, using UK government Livestock Units (LUs) from the 2003 scheme [1] a particular 10 ha (25-acre) pasture field might be able to support 15 adult cattle or 25 horses or 100 sheep: in that scheme each of these would be regarded as being 15 LUs, or 1.5 LUs per hectare (about 0.6 LUs per acre).
The units by which the yield of a crop is usually measured today are kilograms per hectare or bushels per acre.. Long-term cereal yields in the United Kingdom were some 500 kg/ha in Medieval times, jumping to 2000 kg/ha in the Industrial Revolution, and jumping again to 8000 kg/ha in the Green Revolution. [1]
In 2020, the world had a total forest area of 4.06 billion ha, which was 31 percent of the total land area. This area is equivalent to 0.52 ha per person [2] – although forests are not distributed equally among the world's people or geographically. The tropical domain has the largest proportion of the world's forests (45 percent), followed by ...
Stocking measures account for three things: the cover type and species mixture in the stand, the basal area per acre, and the number of trees per acre. [3] Stocking allows for comparing stands that may have diverse ecology. [4] Stocking is a major part of forest management, both in commercial applications and for restoration or preservation.
In Argentina it is a hectare, 10,000 m 2. In most Central American countries it is about 7,000 m 2 (1.7 acres), varying between countries. In Belize it is 8,353 m 2 (2.064 acres). In Nicaragua it is 7,042.25 m 2 (1.74018 acres). If a vara is taken as 83.59 cm, then a manzana of 10,000 square vara s is equal to 6,987.29 m 2.
