Converting the other way: square meters to square kilometers
square kilometers = square meters × 0.000001. So 100,000,000 square meters is back to 100 square kilometers; one square meter is 0.000001 square kilometers. See the square meters to square kilometers table.
Quick estimate in your head
For a rough answer, multiply by about 1000000: 100 × 1000000 ≈ 100,000,000 m2, against the exact 100,000,000 m2 (0.0% out). Good enough to check that a calculated result is sensible.
Common mistakes
The usual slip is using the factor the wrong way round. A square kilometer is bigger than a square meter, so the number of square meters must come out larger than the number of square kilometers. If your answer goes the other way, divide instead of multiplying.
