How to convert square kilometers to square meters
One square kilometer is 1,000,000 square meters, so multiply the number of square kilometers by 1,000,000. For example, 20 square kilometers is 20 × 1,000,000 = 20,000,000 square meters. To go back, divide by the same number, or multiply by 0.000001.
