About Area Converter
Area units are the squares of length units, so their conversion factors are the squared length factors. A square foot is 0.3048 meters squared, which is 0.09290304 square meters.
That squaring is why area conversions grow so quickly. A square kilometer is not a thousand square meters but a million of them, and an acre - defined as 4840 square yards - works out to roughly 4046.86 square meters.
