Quick estimate in your head
For a rough answer, multiply by about 0.000001: 90 × 0.000001 ≈ 0.00009 km2, against the exact 0.00009 km2 (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 meter is smaller than a square kilometer, so the number of square kilometers must come out smaller than the number of square meters. If your answer goes the other way, divide instead of multiplying.
