About This Conversion
Acres to hectares is the land conversion used in agriculture, forestry and property sales. One acre is 4,046.86 m² and one hectare is exactly 10,000 m², so an acre is 0.404686 hectares and a hectare is about 2.471 acres.
The acre is a survivor of medieval field measurement, originally the area one ox team could plough in a day, formalised as one chain by one furlong. The hectare, by contrast, is simply a square 100 m on a side, which is why one converts to a tidy number and the other does not.
The US land survey is built on this unit. A section of the Public Land Survey System is one square mile, 640 acres or 259 hectares, and the quarter section of 160 acres, the classic homestead claim, is 64.75 hectares. Farm listings in the Midwest still describe land in these fractions.
