About Square Feet
A square foot (ft²) is an imperial unit of area equal to a square with sides of one foot (12 in × 12 in or 144 in²). It is the standard for measuring floor space in the United States and some other countries. A typical bedroom is 100-150 ft², and the average American house is roughly 2,000-2,500 ft². This unit dominates real estate listings, flooring sales, and construction in countries using imperial measurements.
About Square Decimeters
A square decimeter (dm²) is a metric area unit equal to 100 square centimeters (10 cm × 10 cm) or 0.01 square meters. It represents roughly the footprint of a large paperback book or a standard floor tile. While less common in everyday language than cm² or m², square decimeters appear in cooking (pan sizes), packaging design, and as a useful stepping stone in metric calculations - notably, exactly 1 liter of liquid forms a layer 1 dm² × 1 cm deep.
