Square kilometers to square meters (km2 to m2) area units conversion factor is 1 000 000. To find out how many square meters in square kilometers, multiply by the conversion factor or use the converter.
1 Square Kilometer = 1 000 000 Square Meters
There are 1000000 (one million) square meters in a square kilometer, because one kilometer is 1000 meters and the area of a square is calculated by multiplying a side by itself, that makes 1000 * 1000 = 1 000 000 square meters in a square kilometer.
For example, to find out how many sq. meters there are in a square kilometer and a half, multiply the sq. kilometer value by one million, that makes 1.5 km2 * 1000000 = 1 500 000 sq. meters in 1.5 sq. kilometers.
