An acre (ac) is equal to one 160th part of a quarter section or one 640th part of a square mile. Thus, the acre has the area of a square with a side length of about 63.62 meters.

1 ac ≈ 63,62 m × 63,62 m

The unit acre (Old English æcer acre, field) originally referred to a strip of land that could be plowed in one day with a team of oxen.

The unit of area known as the acre is now a common unit for subdividing land areas, especially in America. These are initially divided into square miles (sections) and into quarters of these sections, namely quarters. A quarter section, in turn, consists of 160 acres. In the Anglo-American world, the size of properties in land and property surveys is indicated solely by the two area units acre and square foot.

1/640 square mile = 1/160 quarter = 1 acre = 4.840 square yards = 43.560 square feet = 6.272.640 square inches = 4.046,85642 m²

One hectare (ha) is equal to the area of a square with sides 100 meters long.

1 ha = 100 m × 100 m

The hectare belongs to the International System of Units (SI), because it is a unit of measurement of area derived from a multiple of the meter or square meter.

The hectare is most commonly used in agriculture and forestry, where units of 100 by 100 meters, or 10,000 square meters, are in practical use.

Typical orders of magnitude measured or represented in hectares are, for example, the area of a polo field with 4.86 ha or with 1.5 ha the footprint of St. Peterss Basilica. It is also often asked: how many soccer fields are one hectare? The size of a standard soccer field is 0.714 hectares.
