## How to Convert Square Centimeters to Square Kilometers

To convert a square centimeter measurement to a square kilometer measurement, divide the area by the conversion ratio.

Since one square kilometer is equal to 10,000,000,000 square centimeters, you can use this simple formula to convert:

square kilometers = square centimeters ÷ 10,000,000,000

The area in square kilometers is equal to the square centimeters divided by 10,000,000,000.

For example, here's how to convert 500,000 square centimeters to square kilometers using the formula above.
500,000 sq cm = (500,000 ÷ 10,000,000,000) = 5.0E-5 sq km
