Acres, hectares, square meters and feet: compare any surface at a glance.
Area is where the stakes get expensive: land prices, apartment sizes, agricultural yields. The US measures in acres and square feet, most of the world in hectares and square meters — and none of them convert roundly. An acre is 4,046.86 m², a hectare is 2.471 acres, and "looks about the same" costs real money in real estate.
The converters below give exact figures for property, farming and DIY, with tables sized for the amounts people actually search: apartment floors, garden plots, building lots.
Whether you're comparing apartment sizes, pricing farmland or planning a garden, these converters give exact answers across square meters, square feet, acres and hectares. Tables are built around the amounts people actually deal with — a 50 m² studio, a half-acre lot, a 10-hectare field — so you can sanity-check any listing in seconds.
