Acre
Acre (pronounced: /ˈɑːkər/), is a unit of land area used in the imperial and US customary systems. It is traditionally defined as the area of one chain by one furlong (66 by 660 feet), which is exactly equal to 10 square chains, 1⁄640 of a square mile, or 43,560 square feet, and approximately 4,047 m², or about 40% of a hectare.
The etymology of the word 'acre' can be traced back to the Old English word 'æcer', which means 'open field'. The word 'æcer' is derived from the Proto-Germanic '*akraz', meaning 'field, pasture', which in turn comes from Proto-Indo-European '*h₂éǵros', meaning 'field'.
