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.
About Acre (ac)
An imperial unit of land area equal to 43,560 square feet (about 4,047 m² or 0.405 hectares), historically defined as the area one ox-team could plow in a day. The acre remains the standard US and UK unit for agricultural land, real estate over a certain size, forestry, ranch/farm sales, zoning, and golf-course dimensions. A US football field (including end zones) is about 1.32 acres; Central Park in New York is 843 acres.
