Square kilometers to square centimeters
square centimeters = square kilometers × 10,000,000,000
How to convert square kilometers to square centimeters
One square kilometer is 10,000,000,000 square centimeters, so multiply the number of square kilometers by 10,000,000,000. For example, 20 square kilometers is 20 × 10,000,000,000 = 200,000,000,000 square centimeters. To go back, divide by the same number, or multiply by 1e-10.
