Square Kilometer (km²)

A square kilometer is a metric unit of area equal to the area of a square with sides measuring one kilometer. It equals 1,000,000 square meters and is commonly used for large geographic areas, cities, and counties.

1 square kilometer = 1,000,000 square meters = 100 hectares = 0.386102 square miles = 247.105 acres

Common Use Cases

  • Regional and city-scale reporting.
  • Comparing building m² to district km².
  • GIS normalization.
  • Science and geography coursework.

Understanding the Conversion

1 km² = 1,000,000 m². Divide m² by 1,000,000 for km².

Examples: 1,000,000 m² = 1 km² · 500,000 m² = 0.5 km² · 10,000 m² = 0.01 km².

Use when plot or floor data is in m² but regional stats use km².
