Quick estimate in your head
For a rough answer, multiply by about 600000: 40 × 600000 ≈ 24,000,000 s, against the exact 24,192,000 s (0.8% 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 second, so the number of seconds must come out larger than the number of weeks. If your answer goes the other way, divide instead of multiplying.
