m² = km² × 1000000A square kilometer is 1 million square meters — roughly the area of a small town or large estate. Converting km² to m² means multiplying by 1 million. City planners, geographers, and environmental scientists work with both scales when analyzing urban areas, watersheds, or regional land use.
