Area units are easy to confuse because their names hide very different magnitudes — a hectare is ten thousand square metres, an acre is over forty thousand square feet. This converter makes land and floor-area conversions instant.
Base unit conversion
All area units resolve to the square metre. Each has a fixed factor: cm² is 10⁻⁴ m², ft² is about 0.0929 m², an acre is 4,046.86 m². Converting any unit to any other is just dividing by the two factors.
Land units: acre vs hectare
The acre (imperial) and hectare (metric) are the classic land units. A hectare is 100 m × 100 m and equals exactly 10,000 m²; an acre is the historical strip-ploughing measure at 4,047 m². The 1:2.471 ratio between them trips up property comparisons across systems.
