Quick estimate in your head

For a rough answer, multiply by about 7: 15 × 7 ≈ 105 d, against the exact 105 d (0.0% 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 week is bigger than a day, so the number of days must come out larger than the number of weeks. If your answer goes the other way, divide instead of multiplying.
