Quick estimate in your head

For a rough answer, multiply by about 0.0001: 15 × 0.0001 ≈ 0.0015 yr, against the exact 0.00171116 yr (12.3% 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 hour is smaller than a year, so the number of years must come out smaller than the number of hours. If your answer goes the other way, divide instead of multiplying.
