Quick estimate in your head

For a rough answer, multiply by about 5000: 70 × 5000 ≈ 350,000 yd2, against the exact 338,800 yd2 (3.3% 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 bigger than a square yard, so the number of square yards must come out larger than the number of acres. If your answer goes the other way, divide instead of multiplying.
