This converter turns a single area value into every other supported unit at once. Type a number, choose the unit it is in, and the full conversion table updates as you type. It covers metric units — square kilometre, hectare, square metre, square centimetre — and imperial and land units — square mile, acre, square foot. Each conversion goes through square metres as a common base, so results stay consistent no matter which unit you start from. Everything runs in your browser and nothing you type is uploaded anywhere.
