How to Convert Square Meters to Square Kilometers

To convert a measurement in square meters to a measurement in square kilometers, divide the area by the following conversion ratio: 1,000,000 square meters/square kilometer.

Since one square kilometer is equal to 1,000,000 square meters, you can use this simple formula to convert:

square kilometers = square meters ÷ 1,000,000

The area in square kilometers is equal to the area in square meters divided by 1,000,000.

For example, here's how to convert 5,000 square meters to square kilometers using the formula above.

square kilometers = (5,000 sq m ÷ 1,000,000) = 0.005 sq km
