About Square Foot (ft²)
An imperial unit of area equal to a square with 1-foot sides (approximately 0.0929 square meters). Square feet are the dominant unit for US real estate listings ("1,800 sqft home"), commercial office leases, and residential construction — where a home's price per square foot is a universal comparability metric. Also used for paint coverage, flooring estimates, and landscaping bids throughout the United States and parts of Canada and the UK.
About Square Kilometer (km²)
A metric unit of area equal to 1,000,000 square meters, or a square with 1-kilometer sides. Square kilometers are the default unit for geographic scale: country sizes, forest and agricultural land, urban footprints, lake and watershed areas, and deforestation/fire reporting in news and satellite imagery. Manhattan is about 59 km²; New York City is 784 km²; France is 643,801 km². The km² is the preferred unit in most international geographic statistics.
