Quick estimate in your head
For a rough answer, multiply by about 300: 4 × 300 ≈ 1,200 ha, against the exact 1,036 ha (15.8% 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 mile is bigger than a hectare, so the number of hectares must come out larger than the number of square miles. If your answer goes the other way, divide instead of multiplying.
