Quick estimate in your head

For a rough answer, multiply by about 20: 400 × 20 ≈ 8,000 oz, against the exact 6,400 oz (25.0% 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 pound is bigger than a ounce, so the number of ounces must come out larger than the number of pounds. If your answer goes the other way, divide instead of multiplying.
