1 square kilometer equals exactly

1.000.000 square meters

How to Convert Square Kilometers to Square Meters

The square kilometer (km²) and the square meter (m²) are both units of the International System. Since one kilometer equals 1,000 meters, a square kilometer (a square with 1-km sides) corresponds to a square with 1,000-meter sides, which is 1,000 × 1,000 = 1,000,000 square meters.

The Conversion Formula

To convert a measurement from square kilometers to square meters, simply multiply the value in square kilometers by 1,000,000:

square meters = square kilometers × 1,000,000

To convert from square meters to square kilometers, perform the inverse operation, dividing by 1,000,000:

square kilometers = square meters ÷ 1,000,000

Practical Examples

  • 1 km² = 1,000,000 m²
  • 0.5 km² = 500,000 m²
  • 2 km² = 2,000,000 m²
  • 10 km² = 10,000,000 m²

When Square Kilometers and Square Meters Are Used

The square kilometer is the standard unit for indicating the extent of cities, regions, natural parks, or entire nations, while the square meter is better suited for the area of buildings, apartments, or small plots of land. This conversion is common in geography, demographics (for calculating population density), and urban planning.
