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).
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 ...
The square kilometre (square kilometer in American spelling; symbol: km 2) is a multiple of the square metre, the SI unit of area or surface area. In the SI unit of area (m 2), 1 km 2 is equal to 1M(m 2). 1 km 2 is equal to: 1,000,000 square metres (m 2) 100 hectares (ha) It is also approximately equal to: 0.3861 square miles [2] 247.1 acres [3 ...
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.

Square miles should not be confused with miles square, a square region with each side having a length of the value given. For example, a region which is 20 miles square (20 miles × 20 miles) has an area of 400 sq mi; a rectangle of measuring 10 miles × 40 miles also has an area of 400 sq mi, but is not 20 miles square.
The unit is still in use in many areas previously ruled by the Ottomans, although the new or metric dunam has been redefined (as of when, by who?) as exactly one decare (1,000 square metres [10,760 square feet]), which is 1/10 hectare (1/10 × 10,000 square metres [107,640 square feet]), like the modern Greek royal stremma.
