How Many Square Meters in Half an Acre?

There are 2,023.43 square meters in half an acre. A half-acre is also equal to an area of 0.2 hectare, 2,420 square yards or 21,780 square feet.

The acre has been used as a measurement of area since the Middle Ages, but the exact size of an acre was not standardized to a measurement of 4,840 square yards until the British Weights and Measures Act of 1878. The medieval acre equated to the amount of land that a yoke of oxen were able to till in a day. The word "acre" is derived from the Old English word "æcer," which meant an open field.
