About Square Meter ()

The SI derived unit of area, equal to a square with sides of one meter. Square meters are the global standard for floor-plan area in real estate, room measurements, building codes, and scientific work. A typical hotel room is about 25 m²; a basketball court is 420 m²; a standard ISO shipping container floor is ~14.5 m². The square meter is the base unit for every SI-derived areal quantity including pressure, surface tension, and heat flux.

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.
