Quick estimate in your head
For a rough answer, multiply by about 0.00001: 40 × 0.00001 ≈ 0.0004 d, against the exact 0.00046296 d (13.6% 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 second is smaller than a day, so the number of days must come out smaller than the number of seconds. If your answer goes the other way, divide instead of multiplying.
