Quick estimate in your head

For a rough answer, multiply by about 0.003: 16 × 0.003 ≈ 0.048 yr, against the exact 0.04380561 yr (9.6% 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 smaller than a year, so the number of years must come out smaller than the number of days. If your answer goes the other way, divide instead of multiplying.
