One is 43,560 square feet, the other is 10,000 square meters
The acre is exactly 43,560 square feet — a chain by a furlong, inherited rather than designed. The hectare is a square hectometer, 10,000 m², designed rather than inherited. One hectare is about 2.471 acres. Neither is an SI unit, and both are still how land is priced.
