Quick estimate in your head

For a rough answer, multiply by about 20: 1,000 × 20 ≈ 20,000 h, against the exact 24,000 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.
