Quick estimate in your head

For a rough answer, multiply by about 20: 19 × 20 ≈ 380 h, against the exact 456 h (16.7% 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 day is bigger than a hour, so the number of hours must come out larger than the number of days. If your answer goes the other way, divide instead of multiplying.
