About Square Meter and Square Kilometer
The square meter is the SI derived unit of area, the area of a square one meter on each side. Apartment listings, building plans, and material quantities use it in metric countries. The square kilometer is one million square meters. Geography uses it for cities, lakes, parks, and countries, anything too large for hectares. One Square Meter equals 0.000001 Square Kilometers (1 m2 = 0.000001 km2). Square Meter is used in apartment and house listings outside the US and in flooring and paint coverage. Square Kilometer is used in city and country land areas.
Precision and Rounding:Area factors are the squares of exact length factors, so they are exact too (1 ft² = 0.09290304 m² precisely). Whole numbers usually suffice for rooms and land parcels; surveying and legal land descriptions carry four or more decimal places.
Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
