explain to me how shit like this still exists in 2015
The are (/ˈɑr/; or /ˈɛər/ symbol a) is a unit of area, equal to 100 square metres (10 m × 10 m), used for measuring land area.
1 a = 100 m2
1 a = 0.01 ha
1 a = 0.0001 km2
The hectare (/ˈhɛktɛər/ or /ˈhɛktɑr/; symbol ha) is an SI accepted metric system unit of area equal to 100 ares.
ok seems reasonable, let's look at how the yanks do it
The acre is a unit of land area defined as the area of 1 chain (22 yards) by 1 furlong (220 yards), which is exactly equal to 1⁄640 of a square mile or 43,560 square feet. One acre equals 0.0015625 square miles, 4,840 square yards, 43,560 square feet or about 4,047 square metres (0.405 hectares). 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 on which yard it is based. 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. A square enclosing one acre is approximately 69.57 yards, or 208 feet 9 inches (63.63 metres) on a side.
furlongs? perches? chains? is this a joke?
