Quick estimate in your head

For a rough answer, multiply by about 9000: 250 × 9000 ≈ 2,250,000 h, against the exact 2,191,500 h (2.7% 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 year is bigger than a hour, so the number of hours must come out larger than the number of years. If your answer goes the other way, divide instead of multiplying.
