Quick estimate in your head
For a rough answer, multiply by about 0.004: 200 × 0.004 ≈ 0.8 km2, against the exact 0.80937128 km2 (1.2% 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 acre is smaller than a square kilometer, so the number of square kilometers must come out smaller than the number of acres. If your answer goes the other way, divide instead of multiplying.
