Global hectare The global hectare (gha) is a measurement unit for the ecological footprint of people or activities and the biocapacity of the earth or its regions. One global hectare is the world's annual amount of biological production for human use and human waste assimilation, per hectare of biologically productive land and fisheries. It measures production and consumption of different products. It starts with the total biological production and waste assimilation"
"Hectare The hectare (; SI symbol: ha) is an SI accepted metric system unit of area equal to a square with 100-metre sides, or 10,000 m, and is primarily used in the measurement of land.

This dimension of the ""centuria"" became prevalent in the period when the large areas of the Po Valley were delimited, while smaller centuries of 10 × 10 ""actus"", as the name ""centuria"" suggests, had formerly been used. The land was divided after the completion of the roads. Each century was divided into 10 strips, lying parallel to the ""cardo"" and the ""decumanus"", with a distance between them of 2 ""actus"" (71.04 m), thus forming 100 squares (""heredia"") of about 0.5 hectares each: 100 ""heredia"" = 1 ""centuria"".

"divisions of land area were typically based on the square mile, and fractions thereof. If the square mile is divided into quarters, each quarter has a side length of mile (880 yards) and is square mile in area, or 160 acres. These subunits would typically then again be divided into quarters, with each side being mile long, and being of a square mile in area, or 40 acres. In the United States, farmland was typically divided as such, and the phrase ""the back 40"" would refer to the 40-acre parcel to the back of the farm. Most of the Canadian"

By 1827, when new plans were drawn, the area of the Square had been more than doubled and its shape was no longer rectangular. The original Square which Meehan surveyed in 1811 is shown in red hatching on the map below. The only part which remained the same by 1827 was the southern edge, along George Street, although the George Street frontage was now extended to the west to a total of about 230 metres.

This measure was only used in a few countries, but the hectare (100 ares or 10,000 m), is a non-SI unit that has been catalogued as being acceptable for use with the SI"

Originally, an acre was understood as a selion of land sized at forty perches (660 ft, or 1 furlong) long and four perches (66 ft) wide; this may have also been understood as an approximation of the amount of land a yoke of oxen could plough in one day.

"Stremma The stremma ( stremmata; , ""strémma"") is a Greek unit of land area now equal to precisely 1,000 square meters. Its area can be visualized as equal to the area enclosed by a square having side length of 31.62 meters, or 103.7 imperial feet. It is also known as the royal stremma to distinguish it from earlier forms of the unit. The ancient Greek equivalent was the square plethron, which served as the Greeks' form of the acre.

"The square enclosed an area of 50 acres divided in four parts by a North-South axis (the stone gallery) and an East-West axis (the former Roman road, the decumanus). To the north of this square lay the council hall, to the south the Palatine Chapel. The architect drew a triangle toward the East to connect the thermae to the palace complex. The two best-known buildings are the council hall (today disappeared) and the Palatine Chapel, included into the Cathedral. The other buildings are hardly identified. Often built in timber framing, made of wood and brick, they have been destroyed. Lastly,"

At that stage he envisaged it as occupying two whole rectangular sections in the town, constituting the link between the narrow north-east end of the town and the regular, broader grid-plan of the south-west end, set at a slight angle to the north-east part. Meehan measured the Great Square as 15 chains (300 metres) in length by 15.5 chains (310 metres) in depth, although a chain would be taken off on each of the four sides for a"

In practice the hectare is fully derived from the SI, being equivalent to a square hectometre. It is widely used throughout the world for the measurement of large areas of land, and it is the legal unit of measure in domains concerned with land ownership, planning, and management, including law (land deeds), agriculture, forestry, and town planning throughout the European Union.

A shape with an area of three square metres would have the same area as three such squares. In mathematics, the unit square is defined to have area one, and the area of any other shape or surface is a dimensionless real number. There are several well-known formulas for the areas of simple shapes such"
