To convert a measurement in square centimeters to a measurement in square kilometers, divide the area by the following conversion ratio: 10,000,000,000 square centimeters/square kilometer.

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 area in 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.
square kilometers = (500,000 sq cm ÷ 10,000,000,000) = 5.0E-5 sq km

Square centimeters and square kilometers are both units used to measure area. Keep reading to learn more about each unit of measure.
