Every conversion passes through square meters. Metric units use exact powers of ten. Imperial area units come from the international inch, which is exactly 25.4 millimeters, so one square foot is exactly 0.09290304 m² and one acre is exactly 4,046.8564224 m².

How many square feet are in one square meter?

How many square feet are in an acre?
One international acre contains exactly 43,560 square feet. It also equals 4,840 square yards or 1/640 of a square mile.
Why do area conversions use squared factors?
Area measures two dimensions. If each side changes by a length factor, the total area changes by that factor twice. For example, one yard is three feet, so one square yard is 3 x 3, or 9 square feet.
