Sobre Esta Calculadora
Area measurements mix metric and imperial units in ways that cause frequent confusion — particularly in real estate and agriculture, where acres are still dominant in the US and UK while most of the world uses hectares and square metres. Even within metric, the jump from m² to km² spans six orders of magnitude, making unit selection consequential.
This converter covers the seven area units most commonly encountered: cm², m², km², ft², acre, hectare, and mile². One acre equals 4,047 m² (or 43,560 ft²); one hectare equals exactly 10,000 m². These definitions are precise and the converter uses them without rounding.
Enter an area in any supported unit and all six others update simultaneously — useful for quickly sanity-checking a land area or translating a property listing into familiar units.
