Livestock grazing comparison units are used for assessing the overall effect on grazing land of different types of animals (or of mixtures of animals), expressed either as a total for a whole field or farm, or as units per hectare (ha) or acre. For example, using UK government Livestock Units (LUs) from the 2003 scheme [1] a particular 10 ha ...
conversion combination output units SI: square kilometre: km2 km 2: US spelling: square kilometer: 1.0 km 2 (0.39 sq mi) km2 sqmi; square metre: m2 m 2: US spelling: square meter: 1.0 m 2 (11 sq ft) m2 sqft; square centimetre: cm2 cm 2: US spelling: square centimeter: 1.0 cm 2 (0.16 sq in) cm2 sqin; square millimetre: mm2 mm 2: US spelling ...
Conversions between units in the metric system are defined by their prefixes (for example, 1 kilogram = 1000 grams, 1 milligram = 0.001 grams) and are thus not listed in this article. Exceptions are made if the unit is commonly known by another name (for example, 1 micron = 10 −6 metre).
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 ...
It is a common way to describe stand density. In forest management, basal area usually refers to merchantable timber and is given on a per hectare or per acre basis. If one cut down all the merchantable trees on an acre at 4.5 feet (1.4 m) off the ground and measured the square inches on the top of each stump (πr*r), added them all together ...
The definition of the are and hectare are strictly in terms of square meters on a plane. I don't believe that the application of these measures to the legal measurement of actual land is in scope for this article, as the issues are the same whether the unit is the square meter, the hectare, the acre, the square mile, etc.
Assuming a 6,000-metre (6,600 yd) 18-hole course, an area of 80 hectares (0.8 square kilometre) needs to be allocated for the course itself. [17] [Note 1] Examples of golf courses that are about one square kilometre include: Manchester Golf Club, UK [18] Northop Country Park, Wales, UK [18] The Trophy Club, Lebanon, Indiana, US [19]
This was an official unit of measurement in South Africa until the 1970s, and was defined in November 2007 by the South African Law Society as having a conversion factor of 1 morgen = 0.856 532 hectares. [28] This unit of measure was also used in the Dutch colonial province of New Netherland (later New York and parts of New England). [29] [30]
